Reviving a broken G5

I've got a dual 1.8GHz G5 thats out of warranty and not quite functional. Its logic board has some bent pins on the main cpu socket, and I can't seem to get them bent into the right shape to work.

Its possible that one of the CPU's is flakey as well. I'm thinking of getting a uniprocessor replacement logic board and trying to revive it.

However, I wanted to make sure I got the right one (I think I need the 233mhz rather than the 167mhz, but not sure), and that the CPU's could be used one at a time with a replacement board.

Is there any other issues I should be worried about? I know the disassembly is fairly tricky, but I've managed to take it apart already and think I'm okay there...

Thanks in advance!
