I have mid 2010 Mini with Snow Leopard with 2GB of RAM. I will get at least 4GB and will get Mountain Lion also, but with RAM being so cheap, would it be worth it to get 8GB of RAM? All I do is use the Mini as a media server and thats all. My wifes iStuff will sync to it also, but other than that all I do with it is play moves that are on it, stream movies and music, watch Hulu and Netflix, and rip moves with Ripit. Also this is probably a dumb questions, but I can get Mountain Lion with an iTunes gift card, right? Thanks!
