I was given a Dell Poweredge R330 server and I'd like to put it to use. It has a single Xeon processor with 32GB Ram and two 450 watt power supplies. I have no real experience with servers like these in the home environment and I'm wondering if it would be a killer for the ol' electric bill. If I use it, I plan to add it to my PVE cluster and it will honestly not have a tremendous load on it for the time being. It has 6 3.5 inch spinning disks in it that I would probably setup as Raid 1. Any thoughts?
