The Macintosh Server G4/500 was designed similarly as its G3 blue and white predecessor, but used a translucent graphite and white case. Internally, it had a 500 MHz PowerPC 7400 G4 processor, 256 MB RAM (512 GB RAM maximum), an 18.0 GB (or 36.0 GB) hard drive, a 5X DVD-ROM drive, and a Rage 128 Pro graphics card. This server is identical to the Power Macintosh G4 series tower, but included faster hard drives, more RAM, and shipped with a server operating system. The two Apple server operating systems of the time included MacOS 8.6 with AppleShare IP 6.3.1 and MacOS X Server.
The front of the Macintosh Server G4 was translucent graphite (gray) with an underlying pinstripe pattern. The top included spaces for two optical drives. This example includes a DVD-ROM drive and no device in the lower available space. Below the optical drives was a speaker, the power button, and two additional smaller buttons—reset and “interrupt” buttons—both used to recover from system-level issues.
The back of the tower included all ports: two FireWire (400) ports, one ethernet port, two USB ports, and stacked 3.5 mm microphone (audio-in) and audio-out jacks. A space for a modem port is included, but unused in this example. Four slots were also available. This model includes slot 1 with a standard VGA port and a DVI port; slot 2 with a high-speed SCSI (LVD/SE) port; while slots 3 and 4 are unused.
The right side of the tower included a latch with a circular rubberized grip that allowed the entire side of the tower to be opened on a hinge, revealing and providing relatively easy access to all internal components. Plug-in slots (such as video, memory, and wireless) were attached to the hinged side, while components such as drives and fans remained attached to the internal metal frame of the tower.
This Macintosh Server G4 includes three internal hard drives.
