Thin Mini-ITX Motherboard Overview [Updated AUG 2024]

THIN MINI-ITX

Primarily, the Thin Mini-ITX form factor and its motherboards are targeted at the business-oriented All-in-One (AIO) market but are also used in 1U rack servers, e.g. NAS, embedded systems, digital signage, and sometimes in mains-powered IoT applications.  They typically have LVD/eDP/LCD panel drivers built-in also and have slightly higher pricing because of this and other embedded features such as a single DC power supply input (which facilitates a smaller case).

BACKGROUND

The Intel Q series motherboard chipsets support the Intel vPro/AMT remote management with KVM over IP (or iKVM) functionality built into the CPU/chipset combination.  This is very convenient for administrators.  For example, with the correct configuration, you can watch a full reboot, manage the BIOS, and install a new OS remotely. http://www.wikiwand.com/en/Intel_Active_Management_Technology

CASE

Typically Thin Mini-ITX cases are smaller based on the thinness of the motherboard, its low profile components and the requirement to use an external power supply that provides a single DC power supply to the motherboard.  These specially designed Thin Mini-ITX cases can be found on Aliexpress, eBay, and Amazon, and since they are smaller, they can be cheaper, around $85 USD or less (including shipping), than some local suppliers (Australia in mind).  A specific example is the Silverstone PT13 with a Silverstone Nitrogen Series NT07-115X cooler.

Rear I/O Plate

Due to the "Thin" aspect, the thickness of the Thin Mini-ITX specification of the rear I/O shield has been reduced in height only from 44mm to 25mm.

All-in-One (AIO) Cases

One of the primary markets for Thin Mini-ITX is the all-in-one (AIO) market, where the PC is hidden inside or behind (in a box) the screen shroud.

Cooling

You can use these known low-profile heatsink/coolers (<=27mm height) such as these:

Silverstone NT07-115X

I have found this one to be the best but a little more expensive.

ID-Cooling IS Series / IS-25i http://www.idcooling.com/Product/detail/id/23/name/IS-25i

ID-Cooling IS Series / IS-20i http://www.idcooling.com/Product/detail/id/24/name/IS-20i (The limitation is this one has a <45W TDP max)

Perhaps other brands also have suitable heatsinks available, but please be very careful of the height. The max thickness is specified as 27mm.  From experience, I have found several that are only a few millimetres more that do not work in some Thin Mini-ITX cases.

A 27mm height CPU cooler with a unique metallic structure supports a very small form factor and up to 70W cooling power.

Note: There is also a smaller 17mm one for <40W TDP CPUs

Undervolting: Here is a guide to BIOS undervolting the CPU for using smaller heatsinks:

The original cooler

The original Intel Thin Mini-ITX specification required the use (or specifically the support for use) of this heatsink hence the edge of board CPU location in the motherboard layout. However, as later-generation CPUs have become lower in power consumption, this is now less important:

Rack mounting

Many 1U rack cases can also be used with a Thin Mini-ITX motherboard https://www.mini-itx.com/store/category?type=case&rack=1&volume=over-0&drive-bays=over-0&sortby=price&page=1

An alternative case with more space for additional cards or whatever. http://www.scorptec.com.au/product/Cases/Mini_ITX/47964-PT12B?gclid=CMm3mNuZ58kCFVgkvQodKsIKmA This style of case is also helpful for an HTPC (i.e., Home Theatre).

STORAGE (non-volatile)

The boot drive is usually an SSD these days

Most (early) Thin Mini-ITX motherboards usually have either a Mini-PCIe PCB SATA mount or (later) an M.2 type-B (aka NGFF) SATA or an M.2 type-M NVME (PCIe 2x/4x) PC mount, rarely you will find two of these options are available.  Then, if you need heftier storage sizes, they may possibly be supplemented with one or sometimes two 2.5" HDD/SSD of a larger size if the specific Mini-ITX case allows for that.

 

 

SATA SSDs Options: Mini-PCIe SATA or mSATA (left), M.2 2242 (not shown) 2260, 2280 SATA, 2.5" SATA

NVME SSD M.2 Type-M 2280, Type-B(+M) 2242, 2260, 2280 SATA drive, Mini-PCIe SATA (mSATA)

 

Mounting a SATA HDD/SSD inside one of the small cases

Many Thin Mini-ITX (also applies to Mini-SFX) cases have limited space for hard drives and solid-state drives. This limited space may require the use of special low-profile and thin SATA cables to connect to the motherboard.  Here are some examples:

https://www.amazon.com/dp/B00HDEBGSQ/
https://www.amazon.com/dp/B01DLWQPJI/

Note: The number and layout of the SATA sockets on the motherboard, where they need to run inside the specific case limitations, and the number of SATA hard drives you will need to install will all determine the particular choices so they don't interfere with each other's adjacent space.  Typically, regular SATA cables are insufficient for use in many smaller cases.

A slimline SATA cable may be necessary for use in the
 Thin Mini-ITX slim height-restricted cases.

AUG 2024 Update - Many SATA III (3.0) cable options are now available on AliExpress for good prices.  Here are three such items with many options:

• https://www.aliexpress.com/item/1005004464609154.html
• https://www.aliexpress.com/item/1005004595704648.html
• https://www.aliexpress.com/item/1005005737517338.html

AliExpress Search: https://www.aliexpress.com/w/wholesale-SATA-3.0-Cable-laptop.html

SATA power cables will depend on the options available on the particular motherboard.  However, many Thin Mini-ITX motherboards utilise smaller PH 2.0mm, 2.54mm (pitch) or the old 2.5mm FDD (floppy) connector rather than the larger Molex or the traditional SATA power connectors.  Usually, a SATA power cable is supplied in the motherboard kit.  However, sometimes you might need to find a custom dual version for the smaller connector (shown below), as there is little room for traditional bulky splitter cables in the small Thin Mini-ITX cases. E.g. https://www.aliexpress.com/item/1005004610001752.html

POWER SUPPLY

Another thing you need to consider is that many of these motherboards run on 19V, and you need an HP/DELL connector style 90-150W with an external power brick with the proper connector on the end.  Some even use alternative power inputs not defined in the Intel System Design Guide (as below).  For example, Gigabyte boards can run on 12-19V and use a more conventional 2.1mm (ID) x 5.5mm (OD) DC input power socket rather than the 7.4mm (OD) x 5.0mm (Inner D) + Inner Pin (0.6mm) DELL/HP style.  

 

 

Others are supplemented by onboard Molex-style power connectors, usually with strict rules about NOT supplying both power inputs from different power sources (refer to their manuals). 

 

 

Some others may break away from the standard and use 20Pin ATX connectors and can often still be supplied from a single rail power supply via a small switchmode adapter,  Something like one of the many options available here http://www.mini-box.com/DC-DC.

 

THIN MINI-ITX SYSTEM DESIGN GUIDE REFERENCES

Intel was the initial instigator of the Thin Mini-ITX Form Factor.  Here are the reference documents:

ALL-IN-ONE (AIO) DISPLAY

An integrated (OEM) LCD display using the LVDS/eDP port

Many, if not most, Thin Mini-ITX motherboards have an internal connection for what is known as an LVDS (Low Voltage Differential Signalling)/eDP (Embedded Display Port) connection along with a typical combination of external digital HDMI, Display Port and/or analogue VGA connections.  The internal LVDS/eDP ports are often accompanied by a matching LED panel backlight driver.  This may require two separate cables; one is used for the LVDS/eDP, and another one for the backlight.  Alternatively, the backlight can also go over a combined LVDS cable, i.e. it is integrated into one cable.  The following diagram attempts to show these different options.

Showing eDP/LVDS and alternative Backlight Control options
(Diagram courtesy of Cadence - link below)

An LVDS/eDP port is essentially an internal subsystem included on the motherboard for integrating (usually) an LCD flat panel display into, directly attached to, or mounted onboard the case (e.g. AIO).  I have only done this once, and it was very complicated to set up.  I would not advise anyone to casually attempt to undertake this as it took me weeks of research and many more months acquiring LCD panels and waiting for special cables to be customised to get it to work.  Each time you change the LCD panel (this is not like an external display) or the motherboard, you need to go through all this work again.  This includes finding a specialist manufacturer of LVDS cables to make one for your specific display and motherboard combination.  There are only some but not comprehensive specific standards at this level.  Note: LVDS is a standardised type of signalling but not a full-blown connector standard, and eDP 1.5 is an electrical standard based in part on the DisplayPort 2.0 standard but without a physical connector standard. I eventually found a source for manufacturing LVDS/eDP cables on Alibaba (they are usually cheaper than non-Chinese sources).  Here is a search link to get you started if you are a masochist:

https://www.alibaba.com/trade/search?SearchText=LVDS+CABLE+thin+mini+ITX

You will need to contact the LVDS cable manufacturer and supply the details (and perhaps a sample) of a suitable LCD panel (finding a suitable and cost-effective one is another arduous task in itself), along with the details of the length (which has restrictions) and the specific motherboard details (possibly also as a sample if they have no experience with the specific motherboard) you are using to drive the display.  Sometimes the LCD panel supplier may also offer LVDS/eDP cable options or recommend an OEM cable supplier. Some more information on LVDS/eDP is available here (it includes the diagram which I included above for convenience):

https://community.cadence.com/cadence_blogs_8/b/fv/posts/embedded-displayport-edp-version-1-5-introduction

The eDP (Embedded DisplayPort) standard does not specify a single standard connector. Instead, it supports various connectors depending on the application and the manufacturer's requirements. For instance, many eDP cables utilise IPEX MicroCoax connectors, and there are options for MicroCoax to standard Discrete Wire Connectors. Additionally, the eDP 1.5 interface is compatible with the DisplayPort 2.0 standard, allowing for flexibility in cable design and connector types. While the screen side (e.g. LCD display panel as per above) of eDP connectors tends to follow a standard, the mainboard side often has a custom pinout.

The pain does not stop there. Once you have the physical and electrical connections sorted, then the fun of finding the correct BIOS settings for the motherboard to talk to and power the display panel itself begins.  That, again, is another painful "learning" task that is different for each combination.  And this all assumes you haven't selected the wrong voltage, crossed a wire and blown up a motherboard and/or a display or two. Once it works, it is pretty gratifying to see your embedded LCD screen working, but just as is finally getting to the destination of any arduous journey.  And as I have already warned, it is indeed arduous. I will unlikely choose to do it again unless I have to do it for >50 systems.  You have been warned!

CPU & MOTHERBOARD (Thin Mini-ITX) COMBINATIONS

In the initial specification, the Thin Mini-ITX motherboards used any of the Intel Series 2 and 3 CPUs listed below.  However, only some of them have the vPro functionality built-in (check them on the Intel Ark website).

 

Intel Socket 1155 motherboards and the series 2 & 3 CPUs

The only first series Thin Mini-ITX motherboards I am aware of that supported Intel vPro:

 

• Intel DQ77KB https://ark.intel.com/products/59046/Intel-Desktop-Board-DQ77KB

And then there are these Gigabyte none-vPro B75 & H77 chipset thin-Mini-ITX boards:

 

• Gigabyte GA-H77TN https://www.gigabyte.com/Motherboard/GA-H77TN-rev-11#ov
• Gigabyte GA-B75TN https://www.gigabyte.com/Motherboard/GA-B75TN-rev-11#ov

 

Missing in action are Asus, MSI, ASRock, and other manufacturers, but these were the early days of the new form factor.

LGA1150 5th Generation CPUs (Broadwell 14nm)

Note: Most 5th-generation CPUs can only be found in a limited range of low-power mobile BGA CPUs (Ball Grid Array CPUs used in AIO, NUCs, embedded or mobile devices).   https://ark.intel.com/products/codename/38530/Broadwell#@desktop

There were only two hard to find socket capable desktop CPUs, but notably, both were low-power none-vPro versions (possibly never released in retail versions):

 

Here is the limited range of LGA1150

#i7 4 Core & 8 Thread

• i7-5775C    none-vPro 37W TDP

#i5 4 Core & 4 Thread

Intel Socket 1151 motherboards and the 6 & 7 series CPUs (June 2018)

 

Intel Socket 1151 and the 6th and 7th Generation CPUs support DDR3 and DDR4 (specifically DDR3+DDR3L+DDR4).

 

These four are the only motherboards I am aware of that do everything the older Intel vPro motherboard did:

 

1. Gigabyte GA-Q170TN

4. DFI SD101/SD103-Q170

https://www.dfi.com/Product/Index/164

(Impressive 15 Year product availability life cycle)

Technically this motherboard does not meet the Thin Mini-ITX form factor specification, but it is similar, the reason is that the CPU location needs to be near the edge for some forms of low profile cooling (as mentioned above). However, as later-generation CPUs have become lower in power consumption, this is now a lot less important.  You can contrast this motherboard's "Thin" approach with the others above and this normal Mini-ITX version https://www.dfi.com/Product/Index/158 from the same manufacturer (DFI).

Other mostly thin but not strictly Intel Thin Mini-ITX specification
These two motherboards do not meet the Thin Mini-ITX form factor specification but are similar, the primary reason is that the CPU location is not near the edge for some forms of low profile cooling options. However, these motherboards also have a full ATX power connector and no rear DC power socket.  They also have vertical mount DRAM SODIMM slots, so it will be challenging to mount them in a thin case, if at all, despite the rear I/O all being low profile like the Thin-ITX standard.  Some sites even list these items as a thin Mini-ITX motherboard, but strictly speaking, they are not.

Only a few H270 or Q270 Thin Mini-ITX motherboards are known of

The main reason is that the 7th-generation processors will work with the 170-chipset motherboards with a BIOS update.  Warning: But be careful when selecting your CPU as you may need access to an older 6th gen CPU to perform the BIOS update prior to a successful POST upon fitting a 7th gen CPU.

WARNING: Intel, as of the LGA1151, no longer allows the Xeon E3 series CPUs to run with the desktop chipset (even without ECC). So you must use an Xeon (server) chipset motherboard.  In prior Intel chipsets, you could use the Xeon CPUs with non-ECC chipsets. To be clear, the new Xeon E3-1286Lv5, E3-1260Lv5, E3-1240Lv5, and E3-1235Lv5 (and later iterations) cannot be used unless on a server chipset motherboard.

LGA1151 8th (& limited 9th Generation) (Coffee Lake 14nm)

Note: Coffee Lake Refresh (CFL-R, 14nm++, 9th Gen Core, October 2018)

WARNING: DO NOT TRY TO FIT THE FOLLOWING CPUs TO OLDER LGA1151 Motherboards. This will also apply to any other >=8th Generation CPUs

 

#i7/i9 8 Core & 8 or 16 Thread (increased core count to compete with AMD Ryzen)

• i9-9900K  (8C/16T) with vPro 95W TDP*
• i9-9900T  (8C/16T) with vPro 35W TDP (Rumoured@Early Feb 2019)
  i7-9700K  (8C/8T)   with vPro 95W TDP*

*Note: THE 95W TDPs ARE UNLIKELY TO BE SUPPORTED** by any Thin Mini-ITX boards, but with underclocking and a BIOS hack, it may be workable.

**Yet my IMB-1215 motherboard runs the 8C/16T i9-9900K (tested) with limitations on power consumption at 75W, so its clock dynamically reduces to compensate for the lack of power and overheating (but it runs fairly noisy).

#i7 6 Core & 12 Thread (increased core count to compete with AMD Ryzen)

• i7-8700    (6C/12T) with vPro <65W TDP
• i7-8700T  (6C/12T) with vPro <35W TDP (TDPc configurable to 25W)
  Note: That is only approx. 6 watts per core or 4 watts configurable

#Xeons

WARNING: Intel, as of the LGA1151, no longer allows the Xeon E3 series CPUs to run with the desktop chipset (even without ECC). So you must use an Xeon (server) chipset motherboard.  In prior Intel chipsets, you could use the Xeon CPUs with non-ECC chipsets. To be clear, the new Xeon E3-1286Lv5, E3-1260Lv5, E3-1240Lv5, and E3-1235Lv5 (and later iterations) cannot be used unless on a server chipset motherboard (e.g. the C246 chipset).

 

Note: It appears (but not confirmed) that both the Server and Desktop chipsets will support Pentium®/Celeron® Processors (but likely with only non-ECC on desktop chipsets).

MOTHERBOARDS: AGAIN, WE PLAY THE WAITING GAME
There are not many new LGA1200 Thin Mini-ITX motherboards in AUG 2020, and still so in APRIL 2022

ASRock
Once again, the ASRock motherboards are out of the gate faster than the others. Unusually some of these DO NOT have a traditional PCIe slot (other than the ability to use the M.2 x4 Gen3 slot with an adapter). I guess cost and space are considerations on these boards; the ASRock industrial versions further below have many more expansion options and other features but will probably cost a lot more and likely be more challenging to find and purchase.
https://www.anandtech.com/show/15797/new-asrock-industrial-q470-h420-and-w480-motherboards-for-intel-xeon-w-1200
 
ASRock H410TM-ITX (H410) https://www.asrock.com/MB/Intel/H410TM-ITX/index.asp#Specification
Note: Supports the use of ECC UDIMM memory without the error correction function
0 x PCIe x16, 0 x mini-PCIe, 1 x M.2 Key E ,1 x M.2 Key M Gen3 (top), 2 x SATA3

ASRock B460TM-ITX (B460) https://www.asrock.com/MB/Intel/B460TM-ITX/index.asp#Specification
Note: Supports the use of ECC UDIMM memory without the error correction function
0 x PCIe x16, 0 x mini-PCIe, 1 x M.2 Key E ,1 x M.2 Key M Gen3 (top), 2 x SATA3

Note: the B460 adds RAID1/0 support on the two SATA3 ports (B in B460 = Business) 
Apart from that, I can't see any other differences.

 

ASROCK H410TM-ITX
Notice there are no PCIe slots at all (but the M.2 could be used with an adapter)

ASRock Industrial also has three (actually six variations due to two different input supply voltages) new motherboards, and all these motherboards have the traditional Thin Mini-ITX PCIe slot (x16) along with 3 other M.2 Gen3 slots.

•  1 x M.2 Key B (3042)  PCIe x1 for WWAN (with a SIM socket) - for mobile data
•  1 x M.2 Key E (2230)  PCIe x1 for WiFi Module
•  1 x M.2 Key M (2080) PCIe x4 for NVME Storage
•  4 x Serial port headers
  
• VGA header
• LVDS display header

These are some of the most highly featured motherboards in the history of the Thin Mini-ITX form factor.  In my opinion, they also have very nice design layouts.

 

ASRock IMB-1223-WV (H420E) https://www.asrockind.com/en-gb/IMB-1223-WV
1 x PCIe x16, 1 x M.2 Key B, 1 x M.2 Key E, 1 x M.2 Key M (All Gen3), 2 x SATA3

ASRock IMB-1222-WV (Q470E) https://www.asrockind.com/en-gb/IMB-1222-WV
1 x PCIe x16, 1 x M.2 Key B, 1 x M.2 Key E, 1 x M.2 Key M (All Gen3), 2 x SATA3

ASRock IMB-X1222-WV* (W480E) https://www.asrockind.com/en-gb/IMB-X1222-WV
1 x PCIe x16, 1 x M.2 Key B, 1 x M.2 Key E, 1 x M.2 Key M (All Gen3), 2 x SATA3

*This last one adds ECC memory support when an XEON (or Pentium) CPU is installed

*Beware: Other chipset motherboards DO NOT support XEONs unless they are specifically designed for XEON support (which is different to how the desktop chipsets worked in the past...refer to previous sections).

Note: the last two both also add these features:

• PCIe x16 Bifurcation options (support riser cards in x8 / x8, x8 / x4 / x4 configurations)
• vPRO/ATM (remote provisioning and management incl iKVM)
• TPM security built-in (the IMB-1223 only has a header)
• Adds a third video Display Port (but it appears they lose the VGA header)

Note: all three motherboards above have the -WV suffix variation for
supporting a Wide Voltage DC input from 12 to 28V.  This will be needed if you want to use a 19V laptop brick or run from a car (13.8V) or truck (27V) supply.

Two of them are also available with a single 12V input (presumably cheaper?) and likely slightly more efficient if you have a steady 12V supply (i.e. mini server farms):

ASROCK IMB-1222
Notice there is a PCIe x16 slot and 3 other M.2 slots

 

WARNING: These series of motherboards are typically EXPENSIVE, especially in small numbers and will likely be hard to purchase, but some have been seen to be available from industrial suppliers for around  ¥2000RMB/ $310USD / $420AUD(@Aug 2021).

Gigabyte

Gigabyte H410 Industrial board GA-IMB410TN-GSM PLUS

https://www.gigabyte.com/Motherboard/GA-IMB410TN-rev-10#ov
(Note: the H410 is a non-vPro chipset)

1 x PCIe x16, 1 x mini PCIe (Gen2), 1 x M.2 Key E, 1 x M.2 Key M (Gen3), 2 x SATA3

Like most industrial motherboards, this will also be hard to purchase and more expensive than OEM or consumer motherboards.  It has been seen on Taobao for around  ¥1100RMB / $170USD / $235AUD(@Aug 2021).

Gigabyte GA-IMB410TN
Notice there is a PCIe x16 slot, a mini PCIe slot and an M.2-Type E slot  
The M.2 Type-M storage slot is on the rear

ECS

ECS H410H6-TI2 (Note: the H410 is a non-vPro chipset)

https://www.ecs.com.tw/ECSWebSite/Product/Product_GALLERY/EN/Motherboard/H410H6-TI2/Socket%201200

0 x PCIe x16, 0 x mini PCIe (Gen2), 1 x M.2 Key E, 1 x M.2 Key M (Gen3), 2 x SATA3

 

Gigabyte GA-IMB410TN
Notice there is not a PCIe x16 slot, but it has an M.2-Type E slot  
and an M.2 Type-M NVME storage slot.

This motherboard has no PCIe x16 slot, so any expansion would have to rely on using PCIe lanes from one of the M.2 slots with an adapter.  With only 1 x Gigabit LAN port, it is an unremarkable motherboard but, as a result, is likely cheaper than most.

ASUS

ASUS PRIME H510T2/CSM (Note: the H510 chipset used is a non-vPro chipset)

https://www.asus.com/supportonly/PRIME%20H510T2CSM/HelpDesk/

0 x PCIe x16, 0 x mini PCIe (Gen2), 1 x M.2 Key E, 1 x M.2 Key M (Gen4), 1 x SATA3

This motherboard appears to be only available in OEM form, and it is so rare that its sparse support page has no photos and a 2-page manual that is only available in Chinese (@Aug 2021).  This will likely be hard to purchase but has been seen on Taobao (where the photos came from) for around ¥800RMB / $ 125 USD / $ 170 AUD (@Aug 2021).

ASUS PRIME H510T2/CSM
Notice there is not a PCIe x16 slot, but it has an M.2-Type E slot  
and an M.2 Type-M NVME (PCIe Gen 4.0) storage slot.

This motherboard has no PCIe x16 slot, so any expansion would have to rely on the PCIe lanes from one of the M.2 slots with the use of an adapter.  This budget motherboard has many video options: 1 rear I/O access HDMI plus another VGA rear I/O output, 1 more on the side, another via an HDMI connector header, and an LDVS header.  I would assume only 2 (from the H510 chipset specs) can be used at any one time.  With only 1 x Gigabit LAN port, it is an unremarkable motherboard.

WARNING: Intel has confirmed that its upcoming 11th generation Rocket Lake-S processor will not be compatible with the budget H410 or B460 chipsets. According to an updated support page cited by VideoCardz, the 400-series chipsets of the company will be getting BIOS updates to assist the brand-new Rocket Lake processors, while the motherboards based on Intel B460 or H410 chipsets will not be compatible with the upcoming 11th-generation Intel Core processors. The company implied that the motherboards, primarily based on H470, Q470, or Z490 chipsets, would receive support.

Note: It appears (but not confirmed) that both the Server and Desktop chipsets will support Pentium®/Celeron® Processors (but likely with only non-ECC on desktop chipsets).

https://www.firstpost.com/tech/news-analysis/intel-confirms-its-11th-gen-processors-will-not-support-budget-chipsets-like-h410-b460-9297931.html

THE GOOD NEWS 

The newer 500 series Intel chipsets (and one might assume any motherboards based on them) are backward compatible and support both the 10th and 11th Generation Intel Core i9/ i7/ i5/ i3 processors and Intel Pentium processors/ Intel Celeron processors in the LGA1200 package.  The specific chipsets are W580 (Xeon/ECC), Q570 (vPro), Z590 (gaming), H570 (mainstream), B560 (budget), and H510 (budget).

Intel Socket 1200 motherboards and series 12 & 13 CPUs (Q4-2021)

Intel moved (@Q4-2021) to a combination of high-power/high-frequency and low-power/high-efficiency cores, breaking the previous Socket 1200 CPUs.  Referred to as P and E cores. This implies a difference for different workloads.  Hence a new Intel® Thread Director is now used to send the right workload to the suitable core at the right time. More information can be found here.

At an initial look, the max TDP of these new chips is very high, which is unlikely to make them good candidates for Thin Mini-ITX motherboards in many higher-end SKUs.  However, they can apparently, under the right circumstances, be run in exceedingly power-efficient modes and may be suitable after all.  Refer to this article: https://www.pcworld.idg.com.au/article/693767/put-down-your-pitchforks-intel-12th-gen-cpus-aren-t-power-hogs/ 

It will likely take some time (@Q4-2021) for the motherboard vendors to work with these new chips with faster DDR 5 (they can opt to use older DDR4) and PCIe Gen 5 and with newer power configurations in the confined motherboard space of the Thin Mini-ITX form factor.

What about AMD's Ryzen AM4/AM5 in a Mini-ITX (thin?)...

THIN MINI-ITX AM4

FEB 2020 - The first signs of AM4 Thin MINI-ITX motherboards show up:

https://www.anandtech.com/show/13885/the-true-shortest-am4-motherboard-thinitx-comes-to-amd

NOTE: APU Only - i.e. GPU enabled Ryzen/Athlon CPUs ONLY:
The Onda B320-IPC (below), the newer ASRock A320TM-ITX and the X300TM-ITX motherboards mentioned below have no obvious GPU expansion slot. While it may be technically possible that one or more may be adapted with suitable adapter/cables into an M.2 slot, it is also possible that the default BIOS may struggle to support this.  Thus, these motherboards officially only support the GPU-enabled CPUs,
otherwise known as APUs.
Refer to the CPU support list here: https://www.asrock.com/mb/AMD/A320TM-ITX/index.asp#CPU

CPU, APU or GPU - What is the difference?

• Onda (Chinese) - B320-IPC (Ver: 1.0) Mini ITX AM4 Motherboard (APU/GPU Enabled CPUs only) http://www.onda.cn/MotherBoard.aspx?t0=%C6%E4%CB%FC&
   

Onda B320-IPC
Note: 2 x M.2 [M+A] and no PCI-E slot and uses an LGA-115X cooler

 

With Ryzen 3000s (i.e., using the AM4 socket), there were initially no Thin Mini-ITX motherboards (@mid-2019), but then ASRock took the brave step to create an AM4-based Thin Mini-ITX motherboard called the A320TM-ITX which loosely conformed to the Thin Mini-ITX specification (originally an Intel standard).  The A320TM-ITX only supports GPU-enabled CPUs (a.k.a, APUs).

Note: I have not yet been able to find a place to purchase one (@Feb-2020).
Except here: https://www.aliexpress.com/item/4000355852427.html

https://www.superbuy.com/en/page/buy?nTag=Home-search&from=search-input&url=https%3A%2F%2Fworld.taobao.com%2Fitem%2F583127994911.htm%3Fspm%3Da21wu.12321156-tw.0.0.1950638fD6ozSR

 

HEATSINK WARNING: One of the unusual approaches the Onda B320-IPC (above) and the newer ASRock A320TM-ITX (below) both take is to dispense with the use of a typical AM4 CPU cooler layout in favour of supporting the existing cohort of thin LGA115X CPU coolers that were specified in the original Intel standard, thus conforming with the original standard.

• ASRock A320TM-ITX
  https://www.asrock.com/mb/AMD/A320TM-ITX/index.asp

ASRock A320TM-ITX
The first mainstream Thin Mini-ITX AM4-based motherboard
Note: 2 x M.2 [M+E] and no PCI-E slot and uses an LGA-115X cooler

 

Note: This motherboard allows the installation of 2 x 32GB SO-DIMMs allowing a massive 64GB of DRAM.   Unfortunately, there is no ECC memory support for DDR4, and instead, only 2933/2667/2400/2133Mhz non-ECC, un-buffered memory is supported.

This motherboard will likely be hard to purchase, but fortunately, it is cost-effective and has been seen on Taobao for around ¥470 RMB/ $73 USD / $100 AUD(@Aug-2021).

CHIPSET NOTE: An unusual approach to the ASRock X300TN-ITX (below) is to dispense using a typical AM4 chipset southbridge.  A Southbridge chipset can be seen on the previous A320TM-ITX on the top left of the image above, covered with a black finned heatsink. This approach reduces cost and power consumption but also potentially some features.  This compromise is like a new feature in itself.

• ASRock X300TM-ITX (adds Renoir APU/GPU support, a USB 3.2 Gen1 Type-C port, but has only 1 x SATA port by default - it would appear 2 can be ordered as an option with larger OEM orders)

ASRock X300TM-ITX
The first to add USB-C to a Thin Mini-ITX AM4-based motherboard
but which dispenses with the Southbridge chipset
(Note: Only 1 x SATA III port, 2 x M.2 [M+E] and
no PCI-E slot and uses an LGA-115X cooler)

 

ASRock X300TM-ITX is the second mainstream Thin Mini-ITX AM4-based motherboard from ASRock.  Unfortunately, again, there is no ECC memory support for DDR4, and instead, only 3200/2933/2667/2400/2133Mhz non-ECC, un-buffered memory is supported.

This motherboard will likely be hard to purchase but, fortunately, is cost-effective and has been seen on Taobao for around ¥580 RMB / $90 USD / $120 AUD(@Aug-2021).

I ordered an ASRock X300TM-ITX (@Aug-2021) from the Taobao site, and surprisingly, the motherboard was only about 60% of the cost of the previous early pricing for the A320TM-ITX I got in 2020. Later in December 2021, I bought a Ryzen 7 5700G CPU, which made for a blazingly fast SFF PC.

CROSSOVER (Not strictly a Thin Mini-ITX motherboard)

• GA-A520I-DASH (Crossover - Not strictly a Thin Mini-ITX motherboard)
  https://www.gigabyte.com/Motherboard/GA-A520I-DASH-rev-10#kf

GA-A520I-DASH
It is not strictly a Thin Mini-ITX AM4-based motherboard but a sort of crossover
Note: it does NOT use the standard heatsink (as per Intel's Thin Mini-ITX guidelines),
i.e. an LGA-115X heatsink, but the more typical AM4 heatsink.

 

GA-A520I-DASH (linked above) is essentially a thinner version of its thicker cousin, the GA-A520i-AC https://www.gigabyte.com/Motherboard/A520I-AC-rev-1x#kf

Both are Ryzen Series 4000 G-series (Renior) Mini-ITX motherboards that use the newer A520 chipset. The -DASH variant is unique from its cousin for a few other reasons a.) it uses 2 x SODIMM memory slots; b.) it generally utilises less height on the rear I/O (except for the 2nd network port, i.e. not absolutely necessary), so it likely to fit (if somewhat reluctantly*) in some/most Thin Mini-ITX cases; c.) it is also unusual in that it has a 19V DC input for use with an external power brick. Then, as you might expect, it still uses the standard AM4 heatsink mount, and unusually, the SODIMM sockets are vertical. However, these can theoretically be loaded with rare, very low-profile (VLP) SODIMMs (refer to the link below) and an equally hard-to-find, very low-profile AM4 heatsink. Gigabyte, fortunately, appears to support ECC memory for DDR4 3200/2933/2667/2400/2133Mhz in both ECC and non-ECC, un-buffered SODIMMs.

*Minor modifications may be required to fit a typical Thin Mini-ITX case.

AM4 very low-profile(30mm) heatsink: http://www.idcooling.com/Product/detail/id/156/name/IS-30
Warning: You will not get a typical Thin Mini-ITX 25mm I/O plate to support this configuration in the motherboard box. So you must do without or create a self-manufactured one (e.g. 3D print).

Best of all, you can optionally connect a GPU to the x16 slot if you want to build a small but more powerful gaming configuration.  It also has a TPM2.0 controller (which may be necessary in some use cases for future Windows 11 support).

UPDATE @April-2022 - DEAD IN THE WATER - Still no sign of this motherboard available anywhere after 8 months.  It is hard to believe this is so despite Gigabyte recently updating the BIOS of the old AM4 motherboards to support the latest Zen 3 CPUs right up to the R9-5950X (assuming TDP power can be handled).  According to the Gigabyte support site, the BIOS for this impossible-to-find motherboard still only supports the 4 series PRO GPUs, specifically only the R7 PRO 4750G, R7 PRO 4750GE, R5 PRO 4650G, R5 PRO 4650GE, R3 PRO 4350GE and R3 PRO 4350G which I assume means it is not seriously being supported other than possibly for OEM.

UPDATE @Mid-2024 - Can be found (a bit too late to be useful) on Taobao:

https://detail.tmall.com/item.htm?id=742377142608

BIOS also now supports many newer CPUs up to the Ryzen 9 5950X
https://www.gigabyte.com/Motherboard/GA-A520I-DASH-rev-10/support#support-cpu

Note: AM4 support for ECC (error-correcting code) memory support/use depends on both the motherboard chipset (and BIOS) being a high-end one and also the CPU(APU) being a high-end one (usually a PRO edition) supporting it.  Refer to this link for a table showing compatibility https://www.asus.com/support/FAQ/1045186.

What about AMD's Ryzen AM5 in a Mini-ITX (thin?)

https://www.tomshardware.com/pc-components/motherboards/asrock-intros-thin-am5-mini-itx-motherboard

NOTE: AMD's AM5 socket is designed for an LGA CPU (like the Intel format)
and not a pinned CPU (PGA) like the AM4 is.

https://www.electronicshub.org/lga-vs-pga/

NOTE: GPU-enabled Ryzen/Athlon CPUs ONLY:
Like the previous X300 motherboards, the X600TM-ITX motherboard mentioned below has no specific GPU expansion slot available. While it may be technically possible that one or more may be adapted with suitable adapter/cables into an M.2 slot (this motherboard has 3 of them), it is likely that the default BIOS will struggle to support this. Thus, these motherboards officially only support the GPU-enabled CPUs.
Refer to the CPU support list here: https://www.asrock.com/MB/AMD/X600TM-ITX/index.asp

• ASRock - X600TM-ITX Thin Mini ITX AM5 Motherboard (for <65W GPU Enabled CPUs only) https://www.asrock.com/MB/AMD/X600TM-ITX/index.asp
   

ASRock - X600TM-ITX

which dispenses with the Southbridge chipset
(Note: 2 x SATA III port, 2 x M.2 [M], 1 x M.2[E] and
no PCI-E slot and uses an LGA-115X cooler)

 

With the initial arrival of the Ryzen 7000 (AM5) in around mid-2022 and later the 8000/9000s (AM5) CPUs, there were initially no Thin Mini-ITX motherboards to be found, but then in mid-2024 ASRock took the brave step to release a complex AM5-based Thin Mini-ITX motherboard called the X600TM-ITX-which loosely conforms to the Thin Mini-ITX specification (originally an Intel standard).
It only supports GPU-enabled CPUs that are rated 65W TDP or less.

What is notable about this motherboard is that seems to be the only AM5 thin available worldwide (@August 2024).  It also has both dual M.2 storage (one underneath) and dual SATA-III ports, an internal USB3 header, up to 4 display ports [ 2xHDMI + 1xHDMI(internal-side) + 1xeDP(LVDS) ], and best of all, it has support for 2 x 48GB SO-DIMMs for up to 96GBs of RAM. Unfortunately, there is no ECC support.
Note: You can buy one at around $200 AUD from the Chinese Taobao site (assuming you can navigate Chinese):

https://s.taobao.com/search?catId=100&from=sea_1_searchbutton&localImgKey=&page=1&q=X600TM-ITX

 

HEATSINK WARNING: 

The ASRock X600TM-ITX above not only DOES NOT support the AM5 heatsink
but also DOES NOT support the traditional earlier Thin Mini-ITX specification's legacy cohort of thin LGA115X (and LGA1200) CPU coolers. 
It requires an updated Intel LGA1700 CPU cooler.  The manual actually says:
"Supports CPU coolers with Intel® LGA1700 (78mm x 78mm) mounting holes"
@AUG 2024 However, I have not yet been able to find any very low-profile LGA1700 CPU coolers (<28mm thick), with only more traditional Mini-ITX CPU low-profile (~37-45mm thick) coolers being available.  These will work in Mini-ITX cases; however, they will not work in most of the thinner Thin Mini-ITX cases.
Example: https://noctua.at/en/nh-l9i-17xx

ASRock also has released another (not strictly thin) Mini-ITX industrial motherboard, which is a full-height version that does not appear to utilise the whole 44mm of the regular full-height backplate.  If installed along with a low-profile AM5 heatsink, a suitable plug-in mini DC power supply and low-profile DDR5 long-DIMMs, it may, however, easily fit in some of the larger "Thin" Mini-ITX cases (e.g. those designed for a 1U rack).

NAS/Firewall/Router options

Most Thin Mini-ITX motherboards are targetted at end-user desktop computing and IoT devices (e.g. intelligent displays and kiosk terminals) and thus usually only support 1 or 2 x 1Gb Ethernet. If you have another use case, like one requiring greater networking throughput like that offered by 2.5Gbit Ethernet, you will likely need to install an add-on M.2 additional networking 2.5/5/10Gb Ethernet expansion adapter card.  Unless you find a motherboard with two or more M.2 type-M slots (with PCIE x4 channels in each), you may not be able to also use the NVME SSD boot option. Note: To achieve 10Gb or multiple 2.5/5Gb Ethernet throughput, an (NVME boot) M.2 type-M PCIE x4 slot will be required. You can, as an option, sacrifice the M.2 WiFi connectivity option, assuming the WiFi option uses a PCIE x2 M.2 type-A/E slot.  If space inside the case allows, utilise a slot key converting style adapter cable (e.g. https://www.adt.link/product/R54SF.html) to then use an NVME SSD boot drive in it.  This approach may require changes to the BIOS.  If you need WiFi, you can always add WiFi back via a mini USB 3.0 port WiFi dongle.

Alternative to the above, you can look for some of the low-profile embedded CPU boards that are focused on NAS and soft Router/Firewall use cases, as the following examples illustrate.  These are not strictly Thin Mini-ITX motherboards but have low profiles.  They do not conform to the full Thin Mini-ITX specification and usually have the 20/24 Pin ATX power connector (i.e., no rear DC port) requiring an additional multiple rail low-profile mini DC power adapter to run off of the single 12V, 15V or 19V DC inputs (refer to the power options section near the top of the post).  Note: These types of networking-oriented boards also typically do not have LVDS/eDP ports.  The motherboard's accessories will also probably not include a Thin Mini-ITX 25mm high shield.  Nor do they likely use the standard Intel 115X very low-profile heatsink (if there is such a thing anymore).
