The 500 MHz model used the 16 MB 128-bit ATI RAGE 128 Ultra graphics chipset, a 24x/8x/4x CD-RW drive, and a PowerPC 750cx processor, which included 256 kB of on-chip level 2 cache.

Announced in February 2001, this revision of the iMac finally brought FireWire to Apple's entire product line, in addition to a dramatic change in the iMac "colors". Apple chose to get rid of Sage and Ruby in favor of "Blue Dalmatian" and "Flower Power", two new patterns that were molded into the case using a technique which took Apple 18 months to perfect.

The higher-end model iMac got a CD-RW drive, an improved (and faster) PPC 750cx processor, which featured an on-chip 1:1 L2 cache, and a speedy new graphics chip (the 750cx and new graphics chip were initially only available on non-North American models.). It featured a 500 MHz processor, 64 MB of RAM, a 20 GB hard drive and a 56 kbps modem, was available in Indigo, Blue Dalmatian or Flower Power, and was priced at $1199.

The low-end iMac was essentially a renamed iMac DV (Summer 2000), with the price cut to $899. It had a 400 MHz processor, 64 MB of RAM, a 10 GB hard drive and a 56 kbps modem, and was available only in Indigo.
