Hi all, I've been researching far and wide about upgrading my CPU. While there's plenty of how-to's and helpful guides out there, I cannot for the life of me find a single store or useful tip on where one can buy a CPU tray. I have a single CPU tray (3.33 6-core) and would like to buy a dual CPU tray (to put two 3.46 chips_. All of the upgrade sites on ebay require to have a dual cpu tray to upgrade (plus they cost way too much) and I am not paying OWC almost 4 grand to upgrade it. I have found only this... http://www.ebay.com/itm/NEW-661-570...757?pt=LH_DefaultDomain_0&hash=item418ea7b4fd ...which *seems* like it can work. Any help would be greatly appreciated. Thank you!
