So I currently have an Apple TV 3. I'm pleased with it but I find that I mainly use AirPlay to view hulu (free from website, not Plus) or other videos that are stored on my MacBook Pro. Off of the ATV itself I use Netflix and sometimes Vevo. So all of these I can get on a Mac Mini and not have to use my MacBook Pro. My question is, how old of a Mac Mini can I get away with doing this? Looking to stay $200 ($150 if I can) and under. I've seen a few decently priced Core Solo and Core Duo on eBay but just afraid that it won't serve me well. Also, if I get the Core Solo or Core Duo and upgrade to Core 2 Duo, would this be a better option? I already have 3GB ram (2gb and 1gb) and a hard drive to upgrade the system with. So that's no problem. Just want to get the right CPU for the price.
