The Power Macintosh G3 300 (B & W) introduced on January 5, 1999 along with the Power Macintosh G3 350 and 400 featured a stunning blue and white case with a ribbed translucent side that sports a blue Apple logo with a bold G3 silk-screened onto the metal case, just visible behind it. These models offer a 100 MHz system bus instead of the 66 MHz bus of the previous beige G3 models. The 400 MHz model has 32 percent faster CPU performance, 52 percent faster disk speed, and a whopping 95 percent faster graphics speed than the older top line Power Macintosh G3/300 MiniTower.

The Power Macintosh G3 was a variation on a popular and successful theme - the iMac. Like the iMac, the G3 was daring, eye-catching, and even a bit shocking. Their whimsical look was a far cry from what people had been conditioned to think of as a professional-looking computer. Apple took its mini-tower concept, so obvious in the older G3 MiniTower, and dared its users to show theirs off. But aesthetics aside, the Power Macintosh G3 was a game-changer for Apple. Apple changed the rules of what a professional computer was supposed to be, rules which were slowly pushing the company into bankruptcy, by producing a new Macintosh line with amazing industrial beauty, substantially improved internal architecture, fast processors, easily assessable interiors, and they did so at a remarkable price for each standard configuration.
