mini-ITX form factor
- 2009-Sep-04: Antec introduced the ISK 300-65 Mini-ITX case in Summer'09, it provides a pretty nice case plus power supply solution for mini-ITX motherboard for under $100. 
- 2009-May-13: The Intel BOXD945GCLF2D is an Atom 330 (i.e. dual core) based mini-ITX format motherboard that is pretty low cost at about $80. 
- 2009-May-13: Zotax makes a number of mini-ITX motherboards (available here) and are now going to offer some Atom+ION solutions too. A number of reviews of the IONITX-A motherboard (which appears capable of BluRay playback) can be found here. 
- 2009-Jan-22: Neuros is adding support for the Wiimote to their LINK.   
- 2008-Oct-11: Portwell is shipping the Nano-8044, this is the first nano-ITX board that is based on the Intel Atom processor. 
- 2008-Sep-17: Neuros is releasing a new version of their OSD device, this adds support for HD video encoding (including recording 720p from component inputs) and is built around a mini-ITX sized motherboard and enclosure. For the $250 price its actually pretty good value just for the case, power supply and motherboard alone. Note, this is not a general purpose motherboard, but does have a processor with 256MB or RAM and flash built in along with 100MHz LAN and hard disk interface so could well be used for other sorts of computer appliances. A good look at the inside of the device is here. The Neuros OSD 2.0 wiki has more information.   
- 2008-Sep-13: In this project the modder combines a 15 inch LCD monitor with a complete mini-ITX system to produce an all-in-one computer.  
- 2008-Aug-13: The Popcorn hour networked media player is now shipping in limited quantities at $179. This supports up to 1080p (both component and HDMI) as well as composite and S-video. It also has two USB ports for adding devices as well it supports an IDE internal drive for more storage. It supports a pretty wide set of CODECS. There's more information on this on the Networked Media Tank support wiki. In May'08 this started to ship in volume, comments from early adopters are pretty positive. A very good review of the Popcorn Hour with some internal pictures, this review has been updated a number of times as the author has worked with different firmware versions. Engadget asks its readers how they would change the Popcorn Hour. The next generation of this (the A-110) went on pre-order in Aug'08 and they are also making a mini-ITX motherboard called the B-110 for home theater applications. CNet takes a look at the A-110.  
- 2008-Jun-20: In June'08 Via updated its mini-ITX form factor to version 2.0. 
- 2008-Jun-07: In June'08 Via announced the mini-ITX 2.0 platform, this increases the specification to the point where HiDef home theatre PCs could be built with mini-ITX components. Discussed here on Slashdot. 
- 2008-May-20: Intel has added an Atom chip to the D945GCLF mini-ITX motherboard, this should improve the CPU performance of the board, perhaps to the point it can play hidef video? It is available here and gets mentioned here along with some other boards (the DG45FC) that might support DVI and HDMI outputs and also here. Discussed here on Slashdot. 
- 2008-May-14: The EPIA PX5000EG is a fan-less Pico-ITX board. 
- 2008-Apr-27: The Intel D201GLY2 motherboard is a mini-ITX board with soldered-on Celeron processor that costs about $80, making it the least expensive mini-ITX solution I know of (Jan'08). SilentPCReview takes a look at the D201GLY and the newer D201GLY2, they ran tests of the board's ability to play HIDEF media (up to 1080p) from files on the hard drive. It was able to handle 720p and 1080p H.264 playback but WMV3 VC-1 encoded files stressed the CPU and there were some dropped frames. Mini-Box has a good performance comparison between a VIA 1.5GHz processor and the Celeron 215 (1.3GHz) processor on the D201GLY, this shows the Celeron solution running at roughly 25W for a full system, versus the VIA solution running at 20W (so the VIA is a bit lower power); however, the Celeron out perfoms the VIA in all benchmarks and often by a 50% to 100% margin. 
- 2007-Dec-27: Here's an interesting twist, for $199 you can buy a mini-ITX motherboard, RAM and disk drive from Walmart, what you do is purchase their Everex green PC, and then gut it for the mini-ITX motherboard that it contains. This gets discussed here on Slashdot. A review of this PC along with more discussion on Slashdot. PCMag didn't find much to like about this system. 
- 2007-Dec-10: VIA has announced ARTIGO a ultra-compact barebones system based on the Pico-ITX motherboard, for about $300 (including case). 
- 2007-Nov-26: MiniPC.ca is a Canadian distributor of mini-ITX related products (cases, motherboards...). 
- 2007-Nov-09: RadiSys has mini-ITX motherboards, as well as other products for embedded applications. 
- 2007-Nov-08: E-itx has a good selection of mini-ITX, nano-ITX and pico-ITX motherboards. 
- 2007-Nov-08: Interlogic has a good selection of mini-ITX motherboards that are Pentium processor based as well as SBCs for embedded applications. 
- 2007-Nov-08: While not strictly mini-ITX in form factor, the gOS Dev Board is a micro-ATX board based on the Via C7 processor, so it has the nice low power characteristics of a mini-ITX board, but it has more slots and it is roughly 1/2 the cost of an equivalent mini-ITX board. So unless you want to put it in a very small case this might be a good choice. Since it has both ATA and SATA connectors if you have a defunct PC you could just remove its motherboard and pop one of these in its place. If this board had DVI or HDMI output it would actually make a reasonable media PC for quite a low price. Discussed here on Slashdot and here on Engadget. 
Jetway is building a
number of mini-ITX boards (including the J7F5 series with DVI and HDMI
ports) and is going to make some small
form factor cases.
In Jan'07 Via announced their Pico-ITX
super small motherboard, only 3.9x2.8 inches, discussed here
on Slashdot. This board has most of its IO on pin headers (just the LAN
and VGA are on conventional connectors). I would have thought that this
is a step backwards, and some USB and audio (and perhaps also a
composite, or component or DVI video) connectors on the board would
have made a lot of sense for the typical sort of things this board
would be used for. Here's one stuffed

Often these mini-ITX type systems are powered by a two stage power
supply arrangement, an external brick does the initial AC to DC
conversion and then an internal DC to DC converter chops things up to
supply the additional voltage levels the computer needs. Here is a very
small DC-DC converter which is available from mini-Box.com.

is a cute little highly integrated motherboard, roughly 6 inches
square (this PDF claims that the mini-ITX board can be mounted in a
FlexATX or MicroATX chassis, perhaps with modification of the mounting

power supplies) .
Here are a number of neat
case projects built around this sort of motherboard. The Lex

is based on the VIA Mini-ITX. The mini-ITX format could also be used to
your own supercomputer cluster. Or you can fit an entire PC
into a Windows XP retail box - not your typical computer case, but the
artical has some interesting custom case building ideas.
- The mini-ITX form factor is showing some promise as the basis for making
low-power dedicated appliance-like PCs. For example one might make:
based on these small motherboards.
- printer server
- file server
- domain controller
- PVR boxes (though this sort of application is going to be pushing
the CPU somewhat)
DTX form factor
In Jan 2007 AMD started to discuss their new DTX
form factor for small form factor motherboards. Discussed here
- 2008-Sep-19: A review of an ECS mini-DTX motherboard P945GC that uses the dual-core Atom 330 processor. The benchmarks show this to be typically about 1/2 to 1/3 the speed of an Athlon X2 4850 processor. Of course this probably uses about 30W less power than the Athlon solution and should be a bit less expensive. 
- 2007-Oct-22: AMD's DTX and mini-DTX form factor have finally reached the public prototype stage, though progress seems pretty slow at 10 months from announcement to only a prototype shipping. 
Intel is also going to have a DTX
motherboard called the D201GGV, should be available in June'07. 
- n May'07 Gigabyte announced a DTX form
motherboard (along with a proposed case design), this is based
around an AMD chipset.
