Although it shares the name of its predecessor, the "Blue" PowerMac G3 is an altogether different animal. Sporting an all new translucent "easy-open" case design (code named "El-Capitan"), the new G3 was the first Apple model to support FireWire, Apple's new high-speed serial standard. It was also the first professional model to include USB, although it also came with a "legacy" ADB port for backwards compatibility. In a controversial move, Apple chose not to include standard serial ports, a floppy drive, or on-board SCSI (Apple instead chose Ultra ATA). An internal Zip was available, however, as were SCSI expansion cards. The G3 was available in a number of configurations, starting at $1599, and rounding out near $5000 for the fully loaded server configuration. In late April, the "Blue" line was speed-bumped by 50 MHz, bringing the high-end model to 450 MHz.

I was wondering if you could add the fact that there was a
silent release to the G3 line, mid 1999.
The ATA chip was changed so it better supported slave
drives etc. you can recognize the rev. B by the hard disk
mount space. The first G3 B&W's had space to mount a single
hard disk to the casing, whilst the second revision had a
complete rack laying under the power suply wich could easily
be taken out and has space to mount 3 or four hard disks.

The silent revision that was noted in the previous comment is very true and the rev. 2 motherboard can be most easily identified by a "402" on the chip closest to the IDE socket on the motherboard.
