http://buffalo.craigslist.org/sys/179097800.html I plan on using it as a home file server and possibly a game server. The processor is 1.8ghz according to the seller and it has no hard drive (I got that covered). I'm guessing the processor is a sempron or XP. Also, if I decide to get this, what should I use for an OS? I'm torn between XP pro for my knowledge of it or a linux distribution.
