iMac G5

Introduced: August 2004
Terminated: May 2005

Description

The first iMac with a G5 processor, the iMac G5 had a new case.  Everything was now contained in a two-inch thick case that also housed the flat-panel monitor.  It was available in three configurations.  The low-end configuration had a 17” LCD, ran at 1.6Ghz, had an 80Gb hard drive and a Combo drive.  The midrange configuration had a 17” LCD, ran at 1.8Ghz, had an 80Gb hard drive and a SuperDrive.  The high-end configuration had a 20” LCD, ran at 1.8Ghz, had a 160Gb hard drive and a SuperDrive.

History

The iMac G4 took its design cues from the Apple Cinema display line and managed to house the entire computer in a very small space.  Additionally, it was a much faster computer than the iMac G4 before it and offered features like a faster memory bus and a new audio port that could act as an optical digital audio output.
