It was hard to get it going... It's plagued with problems:
Memory card reader: It generates no events on card insertion and removal. Very annoying.
On board audio: The ALSA driver can't do 16 bit stereo PCM over OSS emulation on it. So apps like the quake engine can't produce sound on it (ET)
Alsa bug report of the issue
Shuttle support was really responsive if not very useful. They practically told me they expect people to run Windows on these boxes :-D
The sound issue drove me to buy an USB sound solution...
btw.: If you want to use a Razer copperhead mouse with it make sure to flash its firmware (yes, the mouse does have upgradeable fw).
