Hello Kaz. I was wondering if you people are an authorized repair shop? I know there was lots of people on feebay advertising they could fix them . Not sure how many were actually authorized by microsoft though. 100 a week must keep you busy. How much warranty on a repaired unit? gpu and cpu chip? I guess you are referring to the graphics processor module and the heatsink. If the motherboard gets distorted in a repair, the machine will fail again or not work at all.
