Summary: I was going to use some old parts to build a computer for LinuxCNC. Then I saw this board on the LinuxCNC website. It had very low latency times (a good thing for running a CNC machine from a parallel port). For very little investment I was able to build a much better box. I loaded Ubuntu 10.04, the latest release qualified for LinuxCNC. It works great and seems very responsive.
Summary: Order plenty of these with no problems. Its a low-powered, light weight board... for simple task. Video playback and flash games work fine! Wouldn't suggest much of any other kind of gaming on it though. Def order 4-6 GB RAM for it, it'll make a huge difference. Works great with Win7. (probably with Win8 too... though I wont recommend 8 for the life of me! I do like the CPU fan on this one the most, compared to the other mini itx boards.
Summary: Its a great package. I set up mine with Windows 7 All In One 64 Bit with 4GB ram and a SSD Drive. Its a good small desk top. The only issue I have with it, is it does not playback full HD video well while streaming, like Netflix HD. Netflix with HD disabled works fine. Its great for a web surfing machine and office work. For the $75 or so that it cost, its a great machine for my wife. I used it with the following case/power supply combo HEC ITX200A Mini ITX.
Summary: Pros: Fast Boot. Super Quiet Fan. 4 Sata II ports. Dual Bios (Bios Backup - really works.) Mini-Itx size. Low Power draw. No Drama. Recommended build for XPEnology. 3 Year Warranty. Way faster than my old Atom (running WHS 2011.) From the Comments Section: XPEnology has been Nothing but stable, even after a power outage. My build is XPEnology DS3612xs DSM 4.2 build 3211++. Power usage 55.5 watts with 4 HDD, and PSU is a Seasonic SS-300TGW 300W RT.
Summary: Bought this to build a small form factor computer to use as a DVD and iTunes server. Does the job very well. Fiddly to install due to it's small size, but once constructed, forms a solid, reliable base for using as a media server for DLNA streaming.
