The Apple iMac G5 was launched in August 2004 and was the successor to the popular iMac G4.
Again, it offered an all-in-one processor & screen configuration and was the last Apple to use a PowerPC processor.
Later updates to this model saw the processor changed to an Intel Core Duo processor with mixed reaction from the Apple users community.
We have 2 Apple iMac G5's, both with a 24" screen and complete with all the original packaging, media and manuals. (One has a wireless mouse and keyboard)
