The Power Macintosh G4 (Digital Audio) sits at an important transition point in Apple’s pro desktop history: it kept the familiar Graphite G4 tower design, but introduced meaningful under-the-hood upgrades like a faster 133 MHz system bus, improved AGP graphics support, a fourth PCI slot, and Apple’s first built-in SuperDrive on the top configuration. It also fits squarely into Apple’s early-2000s “digital hub” moment, when the company was pushing the Mac as the center of music, video, and disc creation rather than just a traditional desktop computer.
