Hi guys I built an i7 920 PC last january. I was wondering whats the cheapest comparable used mac pro I could get to replace it? Cause Im pretty much done with windows I cant take it anymore haha. I love my Iphone, Mac Book, ATV I want to finally switch all the way over but Mac Pro's have always been out of my price range. was wondering if by shopping used I might be able to pick something comparable up.....Its going to be used specifically as a studio computer running Digidesign Protools.
