Notes

the dual-867 MHz model shipped with 32 MB NVIDIA GeForce4 GX graphics card, had a 133 MHz system bus, used 266 MHz PC2100 DDR SDRAM, and shipped with a CD-RW/DVD-ROM drive.

Announced in August 2002, The PowerMac G4 (Mirrored Drive Doors) included several motherboard enhancements borrowed from the previously released Xserve rackmount server. The bus speed on most models was raised to 166 MHz, and a PC2100/2700 Double Data Rate SDRAM memory bus was included. Dual processors were included across the entire line, as were enhanced graphics cards.

The G4 (MDD) was one of the loudest PowerMacs ever, and gained the nickname "G4 Windtunnel" for this reason (A fan and power supply replacement plan was subsequently offered by Apple). It shipped in three configurations: a dual 867 MHz model, with 256 MB of RAM, a 60 GB hard drive, a CD-RW/DVD-ROM drive, and a 32 MB NVIDIA GeForce4 MX graphics card was $1699; dual 1 and 1.25 GHz models shipped with 256 and 512 MB of RAM, 80 and 120 GB hard drives, a DVD-R/CD-RW "SuperDrive" and an ATI Radeon 9000 Pro graphics card, for $2499 and $3299, respectively. All models were discontinued in January 2003.

In July 2003, with the arrival of the PowerMac G5, the PowerMac G4 (MDD) was revived as the last OS 9 Bootable PowerMac ever. This configuration included a single 1.25 GHz processor, 256 MB of RAM, an 80 GB hard drive and a Combo CD-RW/DVD-ROM drive, for $1299. Dual processor models were made available as BTO configurations.
