Compared to earlier Power Macintosh G3 models, the Power Macintosh G3 (Blue & White) line -- in addition to the even easier-to-upgrade case -- uses generally faster processors, a faster motherboard design with a faster system bus (100 MHz compared to 66 MHz), faster RAM (PC100 compared to PC66), and a faster hard drive standard (Ultra ATA/33 compared to IDE/ATA-2).
