OK I want to buy a used Mac Mini. I have read loads of forums but cannot find my answer. I want use mainly use the mac mini as a itunes, photo and video server, on all the time so I can view play the media via my 2 apple TVs or my ipads. Should I go for A mid 2011 with the Radeon HD 6630M inbuilt. Or is the graphics card not really used for Streaming. Is it used if I am importing HDV video from a Camcorder? (which I will be as I add footage) Or should I go for a Mid 2011 I7 server edition (2 cores rather than the 2 in the other mid 2011) Or should I go for a Late 2012 I5. I cannot afford a late 2012 i7 so that is ruled out. Cheers For you help I am happy for the answer to be, doesnt matter any mac mini will do the streaming fine.
