This is my IBM xSeries 345 home server. I got this from work for free. They were going to throw it away.
**UPDATE: I have tested and installed Ubuntu on the Dell PowerEdge 2500. It runs fine.
**UPDATE: Some specs on the xSeries 345 server.

-Fans 8x [Part Number 06P6250]

I cleared all the disk space and installed Ubuntu 9.04 (Jaunty Jackalope). I currently have a proxy setup on this machine for learning purposes. I also use it as a network storage unit. The LAN is capable of 10/100/1000. I am running a switch that supports 10/100/1000. My Mac also supports 10/100/1000 so I get blazing fast file transfer speeds between the two. I also have two file storage add-on units that I am not using yet.
I also have a Dell PowerEdge 2500 and a Dell PowerEdge 2450. The 2450 is a pile of nothing at the moment. The 2500 appears as if it could run just fine.
