The iMac G3 (Tray-Loading)

The iMac G3 was Apple's new G3 all-in-one. It had tons of new features, and removed all old interfaces. It was released in 1998, and sported a 266Mhz, or 333Mhz PowerPC G3. It also came in five colors: tangerine, blueberry, lime, grape, and strawberry. These were known as the "5 Flavors."
