CPU
CPU	233 and 266 MHz PowerPC G 3 with 512 KB backside L 2 cache; later 300 and 333 MHz with 1 MB. Apple’s exact Mini Tower Service Source confirms all four clocks and the 66 MHz system architecture. The factory processor supplier is not identified per machine.	300 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 512 KB L2 cache and a 64-bit 50 MHz bus. The shared service specifications use the name 603ev; the exact support page and original brochure use 603e.
GPU
GPU	Built-in 2D/3D accelerator with 2 MB SGRAM, expandable to 6 MB. Original maker sheet specifies ATI RAGE II+; later logic boards changed the accelerator. Optional IX Micro 128-bit PCI graphics card has 8 MB EDO VRAM. EveryMac identifies RAGE Pro Turbo in the later 333 MHz configuration.	ATI 3D RAGE II with 2 MB built-in SGRAM, supporting QuickDraw 2D/3D and QuickTime/MPEG-1 acceleration; Apple's exact support table gives 24-bit colour through 832 × 624, 16-bit through 1152 × 870 and 8-bit at 1280 × 1024. The brochure's 24-bit headline ends at 800 × 600.
Memory type
Memory type	Three 168-pin 64-bit JEDEC-standard 3.3 V unbuffered SDRAM DIMM slots; maker-supported maximum 384 MB. Stock memory of 32, 64 or 128 MB is tied to the factory ordering table. Unofficial 768 MB upgrades are excluded.	64 MB supplied in two 168-pin DIMM sockets, no soldered system RAM; up to 128 MB using 5 V buffered EDO DIMMs. The original brochure and service source specify 60 ns or faster EDO memory, while the exact support database lists 70 ns.
Storage type
Storage type	May 1998 Apple factory pairs: 233 MHz/32 MB/4 GB IDE (M6431LL/A); 266 MHz/32 MB/6 GB IDE/Zip/audio-video (M6142LL/A); 266 MHz/128 MB/4 GB Ultra Wide SCSI/additional 8 MB PCI graphics (M6459LL/A); 300 MHz/64 MB/4 GB Ultra Wide SCSI (M6572LL/A); 300 MHz/128 MB/two 4 GB Ultra Wide SCSI drives/additional 8 MB PCI graphics (M6494LL/A). All have 24x CD-ROM. Later 333 MHz/128 MB/9 GB/Zip is from EveryMac’s exact record. Optional drive/RAM cross-products are omitted. Internal 1.44 MB floppy and optional 2x DVD-ROM.	Original US Home Edition M6079LL/A and Canadian launch configuration have a 4 GB IDE drive, 12× tray-loading CD-ROM, 1.44 MB floppy and 100 MB Iomega Zip drive. Later Americas configurations documented by Apple have 6 GB, 24× CD-ROM, Zip and a 56.6 Kbit/s Apple/GV modem with Mac OS 8.0; Latin America uses a 33.6 Kbit/s modem. European 6 GB/24× configurations include video input, TV/FM tuner and Avid Cinema. These are regional configurations of the same 300 MHz model.
Expansion slots
Expansion slots	Three PCI slots accept three 12-inch cards; PERCH I/O card connector and modem slot. Optional SCSI, Ethernet and graphics cards consume PCI slots. Free internal storage bays vary by configuration.	Two PCI 2.0 slots for approximately 7-inch cards with Mac drivers, plus Communications Slot II, video-input slot and TV/FM tuner position. The original Home Edition's modem occupies the communications slot; its Zip drive occupies the pre-cabled 5.25-inch internal SCSI bay. Apple specifies five external SCSI devices with Zip fitted.

Back ports
Back ports	One ADB, one DB-15 monitor, one DB-25 SCSI, two GeoPort-compatible serial ports, 10BASE-T Ethernet and stereo audio input/output. Optional 10/100BASE-T and FireWire cards are excluded from the standard count.	DB-15 monitor output, ADB, DB-25 external SCSI, two GeoPort-compatible serial connectors, PlainTalk-compatible sound input and line-level speaker output. Installing the internal modem leaves one serial port available. The original US Home Edition has a 33.6 Kbit/s data/voice modem with 14.4 Kbit/s fax; the communications slot can instead take Ethernet. Apple's exact support database lists 10BASE-T, while the maker brochure and Canadian Home configuration supply a modem, so Ethernet is not treated as standard for that configuration.
Speakers
Speakers	–	Built-in full-range monophonic speaker acts as a subwoofer when external speakers are connected; balance adjustment operates only with external speakers. 16-bit stereo input/output and SRS 3D surround processing.
Keyboard and mouse
Keyboard and mouse	–	Original US Home Edition includes keyboard, mouse, cables and bundled home software. Monitor, Apple Video System, Avid Cinema and TV/FM tuner are separate options; later European configurations include the multimedia additions described in storage details.
External displays
External displays	Built-in video supports up to 1600 × 1200, with colour depth depending on SGRAM. Optional PCI graphics card connects a second monitor.	–

Size and weight detail
Size and weight detail	Maker gives 33.1 lb and 15.2 × 9.6 × 17.8 inches height × width × depth. Main fields are direct conversions using 25.4 mm/inch and 0.45359237 kg/lb; actual weight depends on fitted devices.	Maker brochure gives 40.6 × 19.8 × 42.8 cm (height × width × depth) and 20.2 kg, varying with installed devices. The shared service manual gives 20.18 kg without the CD-ROM; standard complete-unit weight remains unresolved and the headline mass is omitted. Gallery monitor is optional.
Power supply
Power supply	240 W maximum; 100–240 V AC, 50–60 Hz (current Apple Mini Tower support table).	Exact support database and original brochure give 220 W maximum continuous, 100–125 or 200–240 V AC at 47–63 Hz. The shared Service Source instead gives 140 W for the 6500 and 90–130 or 180–264 V; the conflicting ratings are retained, and neither is treated as measured operating consumption.
In the box
In the box	Mac OS 8.0 originally; revised stock includes Mac OS 8.1. November 1997 month is supported by Apple’s opened Store selling the new Desktop/Mini Tower, with stock deliveries in two working days and BTO about two weeks; no exact first delivery day is proven. Server G3 shares the chassis but its bundled server configurations are excluded.	Exact support page lists original software 7.6.1; later regional configurations use Mac OS 8.0. Apple lists 4 April 1997 as introduction, while its Canadian announcement promises limited supply later that spring. The maker's 1997 ordering brochure and contemporary shipping-system list establish retail sale in 1997, but the actual first-sale month remains unresolved.
