This will overview the process to remove and replace the Cooling and Processing unit of the Apple G5. Due to design restrictions of the device it is difficult replace the just processors without permanently damaging the entire unit. So this portion of the guide will only overview removal of the entire unit.

Add Note Edit Step 8  ¶ 

  • Remove the G5 metal cover from the processing/cooling unit of the computer. NOTE: Apple inserted a rather fragile plastic pin that inserts through the top divider shield and clips into a tab on the hidden ledge of this CPU shield. Removing this pin, certainly voided Mac's warranty - but more appropriate for now, voids most after-market insurance plans. A replacement pin (new) is hard to get ahold of, and very few are talented and patient enough to remove this pin without damaging it. Just something to keep in mind. If you have no warranty any longer or don't care, please continue...

  • Pull the metal plate to the left and outward to remove the plate from the processing/cooling unit.
