CPU
CPU	Single 1.6 or 1.8 GHz, or dual 2 GHz PowerPC G5 processors; Apple identifies IBM fabrication. Each physical processor has 512 KB L2 cache. Front-side bus per processor is 800 MHz, 900 MHz or 1 GHz respectively. A dual 1.8 GHz configuration was added on 18 November 2003, available immediately; it remains part of this generation.	225 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 64-bit 50 MHz system bus.
GPU
GPU	Stock 1.6 and 1.8 GHz: NVIDIA GeForce FX 5200 Ultra with 64 MB DDR. Stock dual 2 GHz: ATI Radeon 9600 Pro with 64 MB DDR. November dual 1.8 GHz: GeForce FX 5200 Ultra 64 MB. Optional ATI Radeon 9800 Pro 128 MB.	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 type
Memory type	Single 1.6 GHz: 256 MB DDR333, four DIMM slots, maximum 4 GB. Single 1.8 GHz and dual 2 GHz: 512 MB DDR400, eight slots, maximum 8 GB. November dual 1.8 GHz also has 512 MB DDR400 and an 8 GB maximum. DIMMs are installed in matched pairs. Each configuration retains its stock drive and graphics at base and maximum 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 type
Storage type	Stock 80 GB on the single 1.6 GHz; 160 GB on the single 1.8 GHz, dual 2 GHz and November dual 1.8 GHz. 7200 rpm Serial ATA drives; two internal bays with 150 MB/s interfaces. One optical bay with 4x DVD-R SuperDrive; optional Combo drive and 80, 160 or 250 GB drives.	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 slots
Expansion slots	AGP 8x Pro graphics slot. Single 1.6 GHz has three 64-bit 33 MHz PCI slots; faster original models and the November dual 1.8 GHz have PCI-X slots, two at 100 MHz and one at 133 MHz.	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.

Back ports
Back ports	Two USB 2.0, FireWire 800, FireWire 400, Gigabit Ethernet, V.92 modem, optical Toslink audio input/output and analogue line-in/out. Optional 54 Mbps AirPort Extreme and Bluetooth 1.1 with external antennas. Three chassis USB ports in total; keyboard ports are separate.	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 displays
External displays	ADC and DVI connectors with DVI-to-VGA adapter; two displays in extended desktop or mirrored modes. A second ADC display needs an optional adapter.	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.
Speakers
Speakers	Built-in speaker; external audio can use analogue or optical connections.	Built-in stereo speakers, 16-bit stereo sound input/output and SRS 3D surround processing, with rear stereo speaker output.

Size and weight detail
Size and weight detail	Published height 51.1 cm, width 20.6 cm, depth 47.5 cm; 17.8 kg reference weight varies with configuration.	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
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
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.
Materials
Materials	Aluminium enclosure with separate thermal zones.	–
In the box
In the box	Original models shipped with Mac OS X Jaguar; the November dual 1.8 GHz announcement includes Panther. Apple’s 18 August 2003 shipping release confirms immediate availability of the single-processor models; the original dual 2 GHz was due later that month.	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.
