What are the differences between the original iMac G5 models?

Please note that the original iMac G5 series was introduced on August 31, 2004 and discontinued May 3, 2005.

The original iMac G5 models -- the iMac G5/1.6 17-Inch, G5/1.8 17-Inch, and G5/1.8 20-Inch -- feature a revolutionary design with the entire computer placed behind the flat-panel display in an integrated all-in-one enclosure approximately two inches deep.

Like the aluminium-clad Apple Cinema Displays, the original iMac G5 models are suspended by an aluminum stand with an adjustable hinge, and support the "Video Electronics Standards Association (VESA) mounting interface standard" which makes it easy to mount the system directly on a kiosk, wall, or articulating arm.

The major differences are summarized below in this handy chart:

†These models have a NVIDIA GeForce FX 5200 Ultra with 64 MB of DDR SDRAM.
††All hard drives are 7200 RPM.
*Each system only has an expansion slot for AirPort Extreme (802.11g) and Bluetooth 1.1.
