I followed the directions listed here.

It really works amazingly well. I set it up about two weeks ago, and it's been extremely solid ever since. I love having a server that's dead silent and fairly low powered, but still runs everything that I need it to. My needs aren't all that intense, so I don't need tons of computing power; that's good, since this little guy can't provide much at all

For ~100USD on eBay, these things are getting cheap, and can be great, quiet, good-looking little home servers for most needs!
