The Apple Mac Server G4/400 (AGP Graphics), based on the Sawtooth architecture, features a 400 MHz PowerPC 7400 (G4) processor with the AltiVec "Velocity Engine" vector processing unit and 1 MB of backside cache. It shipped configured with 128 MB or 256 MB of RAM, a 20 GB Ultra ATA/66 hard drive or an 18.0 GB Ultra2 SCSI hard drive (and corresponding PCI card), a 5X DVD-ROM drive, and a Rage 128 Pro graphics card with 16 MB of SDRAM in a translucent "graphite" enclosure with a "fold down door" on the side that makes the system extremely easy to upgrade.

For all practical purposes, all models in the Mac Server G4 series are identical to another model in the Power Macintosh G4 series, but the server models often shipped with larger or faster hard drives and more RAM, and always with pre-installed server software. The Mac Server G4/400 (AGP), in particular, is based on the Power Macintosh G4/400 (AGP), but originally shipped either with a copy of MacOS 8.6 and AppleShare IP 6.3.1 or MacOS X Server.
