I recently came across a bargain on Marktplaats (Dutch Craigslist), a Dell PowerEdge 2950 II with 4* 1TB HDDs. This was a no brainer. Buying the disks alone would cost equally as much. Picked it up a few days ago and the server is running VMware ESXi 5.5. I currently have set up FreeNAS as a VM, it’s running SABnzbd, couchpoatato and sickbeard. I’m planning to make some more VMs to run a VPN and do some backups, but I need to upgrade the CPUs and RAM for that. Right now it only has a dual core xeon x5100 @ 1.8ghz and 5GBs of RAM. The CPUs and RAM are dirtcheap on eBay.
