I Just picked up the Compaq Proliant 5500 server for $30 off of Craigslist today.. 10x 18gb hdds, I think its 1-1.8ghz processor, 1gb RAM. I think I did good finding it XD. I'm going to use it as a web/mail/file/folding server. I just wished I could get it up in my room upstairs tonight to start messing with it, but that thing weighs like 300+lbs
