I'm running a Dell Poweredge too, the ancient SC1420, with dual xeon 3.0Ghz, 1Gb RAM, 2x 1TB SATA, 2x 80GB SCSI which I got for free. However, I dont think it's quiet, in fact, it's pretty damn loud and running quite hot (CPU between 58-68 degrees). But it's running in a room with no aircon or fan so I guess that's the cause. I would advise against getting a server unless u've got some place cool to keep it.
