I scored a Mac Pro 2008 with a broken DVD drive for $115. It has a 2.8GHz Quad Xeon processor. I was wondering if I could upgrade it to 2x3.2GHz Xeons, like Apple used to ship the top-of-the-line 8 Core pro with. I have no problem getting my hands dirty, and I have built many computers. Just wanted to know if this was possible.
