I'd be interested to see how this thing performs.
I have a 1.2GHz C7 based NAS running at the moment. I'm using an EPIA board with built-in gigabit ethernet. Performance is absolutely terrible.
The gigabit LAN seems to be limited to about 30MB/sec, even in artificial tests (iperf etc). I have checked all the settings including jumbo frames. Other machines on the same network can easily hit over 100MB/sec in the same tests and manage 60-70MB/sec regularly with file transfers from SATA HDDs.
The C7 is also amazingly slow. In TrueCrypt it only manages 15MB/sec with assembly code optimised AES, where as a Duron 1.2 hits 35MB/sec.
The on-board video is next to useless. In theory it supports high definition playback with hardware acceleration, but in reality the only thing that actually supports this is an ancient patched version of mplayer for Linux. Certainly no Windows/DXVA support. The CPU is of course far too slow.
Worse still, there seems to be a driver bug where the drive randomly changes into a strange screen mode that my monitor cannot display on boot. Checking the BIOS the video output mysteriously changes from CRT to LCD (even with a CRT attached) and the only way to get it working again is to change the setting back and boot Windows in VGA mode.
I'm going to replace it with either a new socket AM2 system or an old Pentium III 1.3GHz.
