CPUSingle 350, 400, 450 or 500 MHz PowerPC G4 with 1 MB backside L2 cache at half processor speed and 100 MHz system bus. Unknown silicon supplier omitted. Original 500 MHz announcement never shipped; only the actual February 2000 option is represented.Dual 867 MHz, dual 1 GHz or dual 1.25 GHz PowerPC G4 processors; each physical processor has 256 KB on-chip L2 cache. 867 MHz and 1 GHz have 1 MB DDR SRAM L3 per processor; 1.25 GHz has 2 MB. System bus 133 MHz on dual 867, 167 MHz on dual 1/1.25 GHz. CPU count describes physical processors; supplier is not inferred.
GPU16 MB ATI RAGE 128 AGP 2x originally, changed to RAGE 128 Pro in December 1999 (EveryMac). Pro adds DVI and supports up to 1920 × 1200, versus original VGA up to 1600 × 1200.Dual 867 MHz: NVIDIA GeForce4 MX 32 MB DDR. Dual 1/1.25 GHz: ATI Radeon 9000 Pro 64 MB DDR. Optional NVIDIA GeForce4 Ti 128 MB; independent CTO options are not expanded into unsupported stock combinations.
Memory typeFour PC100 DIMM slots, maker-supported maximum 1.5 GB. Base memory varies with dated factory configuration; higher unofficial capacities are excluded.Dual 867 MHz: 256 MB PC2100 DDR SDRAM at 266 MHz. Dual 1 GHz: 256 MB PC2700 DDR at 333 MHz; dual 1.25 GHz: 512 MB PC2700. Four DIMM slots support up to 2 GB. Configurations preserve stock processor/drive/graphics ties at base and maximum memory.
Storage typeDated stock changes (EveryMac): original 450 MHz 128 MB/20 GB/DVD-ROM; October 400 MHz 128 MB/20 GB/DVD-ROM and 450 MHz 256 MB/27 GB/DVD-RAM. December adds 350 MHz 64 MB/10 GB/DVD-ROM and replaces graphics with Pro. February 2000 maker confirms 400 MHz 64 MB/10 GB/DVD-ROM, 450 MHz 128 MB/20 GB/DVD-ROM and 500 MHz 256 MB/27 GB/DVD-RAM. Zip included on original 450, October 400/450, and February 450/500; identical optical-only variants are kept in details. No unproven SCSI/drive cross-combinations.60/80/120 GB 7200 rpm Ultra ATA/100 stock drives respectively. Dual 867 MHz has Combo DVD-ROM/CD-RW (CD-R 16x); faster models SuperDrive (DVD-R 2x, CD-R 8x). Four hard-drive bays support two ATA/100 and two ATA/66 drives, or up to four SCSI drives with a separately sold PCI card. Two optical bays, one occupied; optional second Combo drive. Maker optional storage choices remain in details rather than assumed CPU cross-pairs.
Expansion slotsThree open full-length 64-bit 33 MHz PCI slots and one AGP 2x slot used by graphics.Four open full-length 64-bit 33 MHz PCI slots and dedicated AGP 4x graphics slot.

Size and weight detailExact Japanese maker sheet publishes 43.2 cm height, 22.6 cm width, 46.7 cm depth and 13.6 kg weight; configuration-dependent.Exact maker reference weight 19.1 kg varies with configuration and manufacturing process; height 43.2, width 22.7, depth 46.8 cm. These published dimensions differ slightly from earlier G4 sheets and are retained.
Power supplyMaximum continuous power 200 W.100–125 V AC or 200–240 V AC, 50–60 Hz. Maximum current 6.5 A at low voltage or 7.5 A at high voltage; maker publishes no maximum wattage here.
In the boxMac OS 8.6 originally. September 1999 introduction and a few original 450 MHz channel shipments are documented by Apple-History, but the first shipping month is not established; release stays at year precision. February 2000 maker release confirms immediate availability of the revised range.Mac OS X 10.2 Jaguar as default startup system, plus bootable Mac OS 9.2.2; iMovie, iPhoto, iTunes and iDVD for SuperDrive. Maker August 13 release says dual 867/1 GHz available that week, so first sale uses August month precision. Actual dual-1.25 GHz shipping confirmed 18 September. January 2003 FireWire 800 models and June 2003 reissue are separate generations.
