Good point Charles, I am just not sure an Atom custom build would give as much bang for the bang. I was pricing one to build a firewall/media server/2nd desktop and could not keep under $400, when I trie to get closer to the Mini specs all went to hell, build price skyrocketed... You can get an used Mini for around 400 on eBay..

You do have to be a little careful because the quality of these can vary widely. Mine, for example, refuses to boot from certain hard disks. But like anything else, you have to do your research.
