CPUDual models have one physical dual-core PowerPC G5 at 2 or 2.3 GHz. Quad has two physical dual-core processors at 2.5 GHz, four cores in total. Each core has 1 MB L2 cache. Front-side bus per physical processor is 1, 1.15 or 1.25 GHz respectively. Macworld’s exact Quad review describes its liquid cooling.225 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 64-bit 50 MHz system bus.
GPUStock dual-core 2 GHz: NVIDIA GeForce 6600 LE with 128 MB GDDR SDRAM. Dual-core 2.3 GHz and Quad: NVIDIA GeForce 6600 with 256 MB GDDR SDRAM. Optional NVIDIA GeForce 7800 GT 256 MB and Quadro FX 4500 512 MB; the Quadro occupies the graphics slot and adjacent x4 slot.2 MB built-in SGRAM with hardware 2D and 3D acceleration, including QuickDraw 3D, video capture and QuickTime/MPEG-1 playback. Exact education brochure specifies 24-bit colour through 832 × 624 and 16-bit colour through 1024 × 768. Exact support and shared service tables also list 1152 × 870 at 16-bit and 1280 × 1024 at 8-bit; the brochure does not establish these as built-in CRT modes, so its documented 1024 × 768 display mode is retained as the headline. Display resolution can be changed in software; the CRT has no fixed pixel matrix.
Memory typeStock 512 MB PC2-4200 DDR2 at 533 MHz, installed in matched pairs. Up to 16 GB supported; ECC configurations available from 1 GB. Rows retain the stock drive and graphics at base and maximum supported memory.US education ordering model M5761LL/A has 32 MB RAM; the shared service manual also documents 16 MB configurations sold worldwide. No system RAM is soldered on the logic board. Two 168-pin DIMM slots support up to 128 MB with 5 V, 60 ns or faster EDO DIMMs; the brochure specifies noncomposite modules with 1K or 2K refresh. The service manual supports both fast-page and EDO DIMMs, noting that mixing them can use fast-page timings.
Storage typeStock 160 GB on dual-core 2 GHz and 250 GB on dual-core 2.3 GHz and Quad. 7200 rpm Serial ATA drives; two internal bays. Optional one or two 500 GB drives. One optical bay with 16x SuperDrive supporting dual-layer DVD+R recording.Exact US education brochure specifies a 2 GB IDE hard drive, 12× CD-ROM and 1.44 MB SuperDrive floppy. Exact support and shared service document 24× optical configurations too. Later US education configurations have 32 MB/24× and Mac OS 8.0; Europe has 32 MB/2 GB/24× with a 33.6 Kbit/s modem, while Japan has 32 MB/4 GB/24× with the same modem and Mac OS 8.0.
Expansion slotsPCI Express: occupied x16 graphics slot, two open x4 slots and one open x8 slot. Older PCI and PCI-X expansion cards cannot be reused in these slots.One PCI 2.0 expansion slot for a 7-inch card with a Macintosh driver, Communications Slot II used by the Ethernet card or regional modem, video-input slot and TV/FM tuner bay. The education brochure lists optional Apple TV/FM Radio System and Avid Cinema Video Editing System. The shared service provides a digital-video connector for compatible expansion hardware; it is not compatible with the earlier Quadra 660AV/840AV connector.

Four chassis USB 2.0 ports in total, plus two keyboard USB 1.1 ports. AirPort Extreme and Bluetooth 2.0 + EDR are optional, with integrated antennas; built-in support does not mean modules are included.US education brochure and exact support specify 10BASE-T Ethernet, ADB, external DB-25 SCSI, two RS-232/RS-422/LocalTalk/GeoPort-compatible serial ports, PlainTalk-compatible sound input and stereo output. The Ethernet card occupies Communications Slot II; later European and Japanese configurations instead supply a 33.6 Kbit/s modem. Brochure supports six external SCSI devices. Video-input card is included in the education brochure and accepts composite and S-Video; TV/FM tuner and Avid Cinema are optional.
External displaysStock GeForce 6600 LE/6600 and optional 7800 GT have one single-link and one dual-link DVI port, supporting one 30-inch Apple Cinema HD Display alongside a second display. Optional Quadro FX 4500 has two dual-link DVI outputs for two 30-inch displays and a stereo 3D connector. DVI-to-VGA adapter included.US education brochure includes NTSC TV-output capability for a compatible television, VCR or camcorder. Computer-monitor output requires the appropriate external video connector; the shared service documents video mirroring rather than an independent extended desktop. Regional video bundles vary.
SpeakersBuilt-in speaker and optical/analogue external audio connections.Built-in stereo speakers, 16-bit stereo sound input/output and SRS 3D surround processing, with rear stereo speaker output.
Microphones–Built-in microphone; PlainTalk-compatible external sound input.

Size and weight detail–Exact education brochure gives 44.5 × 38.3 × 40.6 cm (height × width × depth), 21 kg / 47 lb; support database agrees with these inch dimensions and 47 lb. AppleFacts August 1997 second page instead prints tower-like 40.6 × 19.8 × 42.9 cm and 20 kg, inconsistent with its all-in-one identity. The shared service swaps width/depth and prints inconsistent pound weights. Brochure complete-unit measurements are retained, with weight varying by installed devices.
Power supply–Exact support specifies 220 W maximum, 110–240 V AC at 50–60 Hz. The original education brochure separately lists 150 W maximum excluding the display, 110/220 V and 47–63 Hz. Shared service lists 125 W and 220 W maximum for all line/load conditions; these differently qualified ratings are not treated as measured operating consumption.
Noise–Variable-speed fan automatically runs at the lowest speed needed to minimise noise; the processor also has a small cooling fan. No acoustic measurement is published in these sources.

In the boxMac OS X Tiger and iLife ’05. Apple confirmed the dual-core 2 and 2.3 GHz models available on 19 October 2005, with Quad expected in early November. Macs Only reports its Quad shipped on 10 November and arrived on 11 November; these later Quad dates do not change the generation’s first sale. The exact specification sheet does not publish weight or dimensions.Exact support lists original System 7.5.5 and Enabler 411; education brochure lists Mac OS 7.6 or later and describes Mac OS 7.6.1 software, while later service configurations use Mac OS 8.0. Apple records introduction on 17 February 1997, but the August 1997 current ordering brochure and catalogue establish sale only at year precision in this record. Actual first-sale month remains unresolved. Energy Saver schedules sleep, starting up and shutdown.
