Apple Mac Server G3The Apple Mac Server G3/233 Minitower, based on the compact Gossamer architecture, features a 233 MHz PowerPC 750 (G3) processor with 512k of backside cache, 64 MB of RAM, a 4.0 GB Ultra/Wide SCSI hard drive (and corresponding PCI card), a 24X CD-ROM drive, ATI 3D Rage II+ or Rage Pro (starting May 1, 1998) graphics acceleration with 2 MB of VRAM (expandable to 6 MB), and the standard "Whisper personality card" with audio input/output -- all packed into an easily expandable minitower case.

For all practical purposes, all models in the Mac Server G3 series are identical to another model in the Power Macintosh G3 series, but the server models often shipped with faster hard drives and dual Ethernet ports, and always pre-installed server software. The Mac Server G3/233 Minitower, in particular, is based on the Power Macintosh G3/233 Minitower, but originally shipped with a copy of MacOS 8.1 "specifically tuned for server use" and AppleShare IP 5.0 server software.
