The Macintosh Server G3/300 Minitower was released in 1998 as the final beige tower design by Apple. This G3 Server used a 300 MHz PowerPC 750 G3 processor, a single 4.0 GB SCSI hard drive (with space for a second drive), and a 24x CD-ROM drive.
This minitower also contained a “Whisper personality card” that added audio input and output ports. According to LowEndMac, Apple had planned various “personality cards,” but only audio (“Whisper”), audio/video (“Wings”), and audio/video/DVD playback (“Bordeaux”) were ever produced.
The case design of this minitower includes a removable side panel and two internal tabs that, when released, allow the entire tower to tilt 90 degrees on a hinge allowing easy access to all internal components. Interestingly, the side door panel latch and internal tabs are made from translucent blue-green plastic, a design aesthetic that would soon become the Mac design norm that same year when the original iMac was released.
Ports on this computer include SCSI; ADB (Apple Desktop Bus); Ethernet (10-100); Mac serial and printer ports; Apple Video (DB-15), line-out and microphone 3.5 mm jacks. Three card slots are available: the first is empty, but ready for a high-speed SCSI port; the second slot has a second high-speed ethernet port; and the third slot adds two USB ports.
The exact factory configuration of the server is shown as: 1MB Cache/128MB/2x4GB UW/CD/10-100 ENET. The model is M4405, and the serial number area specifies a production date of May 27, 1998, at 3:30 PM.
