I have an iMac 400DV. I have obtained a 600Mhz logic board (with IBM 750) that I want to install to replace my 400 logic board. Everything plugs in like it is supposed to, but the heat sink for the processor is in a different place. Anybody relocated the heat sink yet and is it do-able? How difficult is it to remove the chassis so i can drill new holes? Help and suggestions are welcome...
