Identify your computer …
There are five Power Macintosh G5 generations: Late 2005, Early 2005, Late 2004, June 2004, and the original Power Mac G5 (2003). Major components for each PMG5 (logic boards, processors, etc.) are unique, meaning that you must identify which model Power Mac G5 you have before ordering replacement parts for it.
The information you need to do this - your computer's serial number and processor speed - is printed below the air deflector inside the access panel recess. (Note: power down and unplug your computer before removing the access panel).
