So after tons of thread and google searches on the best way to build a super custom mac computer Im NOW down to the Chips... and no luck with info on that.. other than how outrageously expensive some are....so here I am. So pretty much, Can you Only put Apple-provided Xeon Chips inside of mac pro logic boards, or will it be compatible with Any Xeons? Yes, good. No, why? I dont have a specific board, just looking at ones that are mid 2009 or early 2010...just seeing what I can do. (I hope microsoft and apple havent went to far as to get technical to the point of what chips go in the boards.......or have they?) For those who may say that the money I would spend doing this Could lead up to me being better off buying a new apple....no...lol.... new ones at the cheapest is $2500 bucks. In regards to what all u get, maybe that could be a better route..but thats not the route im looking at right now.
