There have been some topics posted here about people converting their old, under utilized Macs to servers. This might seem like a bizarre question, but I was wondering if things could go the other way and would an Apple Xserve machine be a terrible, decent, or fantastic desktop computer? I was looking at the AppleStore spec.s just now. They have a ton of processing power, most of the standard hardware ports of a Mac, even a cheesy video card for making podcasts, and decent expandability. What am I missing? I know that they are heavy and pricey (compared to a PowerMac though?).
