So at present I'm using a 2007 mini under the stairs as my media server. It's now about to be retired since it can't take the later os's. I now seem to have 3 options. . Buy the new mini even though it's not upgradable . Buy a refurb or used (assuming one can be found for a sensible price) . Buy a mini pc machine. Any recommendations for a pc machine? I'd like to keep the form factor as small as possibles My imac is my main machine so it doesn't need to be a powerhouse Thanks.
