The easiest way to find out is to DL an install image, I would recommend Leo4all V3. But if you can't connect a PCI-E gfx card you'll have no fun with that board. By the way, please expain better for what you want to use it. For using it as an file server the board is too special, I wouldn't use it for this. And if you want to use it as video converter, you need full graphics support.
If you want to use a cheap system as file server, I would recommend a nForce 4 system if you want to use AMD. The prices I list are from Germany.

With a eHome-compatible IR receiver (f.e. from a Windows Media Center remote control) and the software
mira you can control EVERY program with the Apple Remote, not only FrontRow.
And if you need something for video converting, try the Elgato
Turbo.264. It's an USB stick which converts H.264/Mpeg4 by hardware. Some 3rd-party software also support it, f.e. Toast 9.
