Hi, A couple of weeks ago I bought a used 1,1 Mac Pro Quad 2.0 with the intension of removing the 2.0 and upgrading to 3.0. I bought a couple of used x5160's and I've got all the instructions etc to do the upgrade. I've built a few PC's in my time so hopefully finger crossed this will be no problem. I'm looking for a supplier in the UK which can sell the long-handled, magnetized 3 mm flathead hex screwdriver mentioned in the instructions. Do any of you guys know where I can get one? If not what have you guys used to get at these hex bolts? Also tips would be helpful. Thanks in advance. Glyn Jones.
