USB 2.0 | 20-inch Flat Panel | 1.25GHz

The beefy new 20-inch flagship arrived seventy-one days after its USB 2.0 siblings.

With a whopping 1680 by 1050 pixels of real estate, it was the largest iMac ever offered to this point. This series was the first to include USB 2.0 support.

A behemoth not only in size, the 20-inch model set you back an additional $400 over the price of the 17-inch 1.25GHz iMac, with which it shared most components.

Like its 17-inch sibling, this widescreen beauty came equipped with the G4 1.25GHz processor with AltiVec “Velocity Engine” and SuperDrive.

The “runt of the litter” 15-inch 1GHz iMac came with a Combo drive and less capable graphics support.

This model came Airport Extreme ready with a build-to-order option for an internal Bluetooth module. There were two FireWire 400 ports, three USB 2.0 ports (two more USB 1.1 ports on the keyboard), a VGA output port, built-in modem and Ethernet, S-video and composite video output, headphone jack, Apple speaker minijack and audio line-in jack.

This series shares the rear port rearrangement of the previous 17-inch 1GHz model, except with USB 2.0 ports rather than 1.1.

All models in this series came with the Apple Pro Keyboard, Apple Pro Mouse and Apple Pro Speakers.

This model holds both a beginning and an end in iMac history. It was the first 20-inch iMac ever and the last model of the sunflower design. The following year would bring a new design in the form of the G5 iMacs.
