Memory
Memory	512 MB, 4 GB or 8 GB (better)	16 MB
Storage
Storage	160 GB to 250 GB (better)	1.2 GB
CPU
CPU	Two physical PowerPC G5 processors at 2, 2.3 or 2.7 GHz, each with 512 KB L2 cache and no L3 cache. Front-side bus per processor is 1, 1.15 or 1.35 GHz. The dual 2.7 GHz model uses liquid cooling.	120 MHz PowerPC 603e with integrated floating-point unit and 32 KB L1 cache. Exact original brochure and Apple support specify a 64-bit processor data path at 40 MHz. Optional 256 KB L2 High Power Macintosh Module M4849LL/A; it is not included as standard.
GPU
GPU	Dual 2 and 2.3 GHz: ATI Radeon 9600 with 128 MB DDR and two single-link DVI outputs. Dual 2.7 GHz: ATI Radeon 9650 with 256 MB GDDR3, one single-link and one dual-link DVI output. Optional NVIDIA GeForce 6800 Ultra DDL with 256 MB has two dual-link DVI outputs and occupies the adjacent PCI slot.	1 MB built-in DRAM framebuffer; exact support and shared service video-mode list support 640 × 480 with 16-bit colour. Other higher-resolution timing pages in the shared service do not establish those as supported modes for the built-in 14-inch display.
Memory type
Memory type	Stock 512 MB PC3200 DDR400, installed in matched pairs. Dual 2 GHz has four DIMM slots and a 4 GB maximum. Dual 2.3 and 2.7 GHz have eight slots and an 8 GB maximum. Configuration rows keep the stock drives and graphics at base and maximum memory.	16 MB standard, expandable to 64 MB using two 72-pin SIMM sockets; exact support and shared Service Source state no soldered RAM. Original exact brochure specifies 70 ns or faster noncomposite SIMMs, while current support and service specify 80 ns. The 5260-series user manual technical table and exact 5260/120 user-guide update instead state a 12 MB minimum in removable 70 ns fast-page SIMMs without an exact factory-order bundle. November 1996 Apple Facts claims 8 MB on board plus an 8 MB SIMM, contradicting exact support and service. No additional factory configuration is inferred from these disagreements.
Storage type
Storage type	Stock 160 GB on dual 2 GHz and 250 GB on dual 2.3/2.7 GHz, all 7200 rpm Serial ATA. Two internal drive bays; optional 250 or 400 GB drives, including two 400 GB drives. One optical bay with 16x SuperDrive supporting DVD±R and up to 4x dual-layer DVD+R recording.	1.2 GB IDE hard drive and 1.44 MB Apple SuperDrive floppy. Exact current support, TIL 20413 description and original education bundle list an 8× CD-ROM drive; shared Service Source identifies AppleCD 1200i. The September 1996 exact brochure and November 1996 Apple Facts instead say 4× CD-ROM. The optical-drive difference remains source-qualified rather than adding an undocumented factory configuration.
Expansion slots
Expansion slots	AGP 8x Pro graphics slot. Dual 2 GHz has three 64-bit 33 MHz PCI slots. Dual 2.3 and 2.7 GHz have PCI-X: two 100 MHz slots and one 133 MHz slot.	LC-compatible PDS, 68040-bus communications slot for optional modem or Ethernet, optional video-input card and TV tuner bay. PDS is not a direct connection to the PowerPC processor; processor-dependent cache/FPU cards are not compatible. Optional MPEG Media System requires the video-input card. Video capture accepts NTSC, PAL and SECAM; tuner standard varies by region.

Display type
Display type	–	Built-in 14-inch nominal shadow-mask colour CRT with 12.3-inch viewable diagonal in the exact original brochure and product description. Shared Service Source instead says 12.8-inch viewable; exact model wording is retained. Dot pitch 0.28 mm; tilt-and-swivel base.
Display features
Display features	–	640 × 480 at 16-bit colour and 66.67 Hz in the exact original brochure. The shared service agrees on 66.7 Hz. This is a CRT raster mode, not an LCD fixed pixel grid.

Front ports
Front ports	USB 2.0, FireWire 400 and headphone minijack.	Headphone output, push-button volume and display brightness controls, infrared remote receiver.
Back ports
Back ports	Two USB 2.0, FireWire 800, FireWire 400, Gigabit Ethernet, optical S/PDIF input/output and analogue audio line-in/out. Three chassis USB ports in total, plus keyboard USB 1.1 ports. AirPort Extreme, Bluetooth 2.0 + EDR and a V.92 modem are optional.	ADB, external DB-25 SCSI, two RS-232/422 modem/printer serial ports with LocalTalk, PlainTalk-compatible sound input and stereo sound output. Ethernet requires an optional communications-slot card; no GeoPort. Original exact brochure and maker catalogue specify five external SCSI devices; the shared user manual gives six and shared service gives seven, so limits remain source-qualified.
External displays
External displays	Two displays in extended desktop or mirrored modes. Radeon 9600 supports two displays up to 1920 × 1200; Radeon 9650 supports one 30-inch Apple Cinema HD Display via dual-link DVI. Optional 6800 Ultra DDL supports two 30-inch displays. DVI-to-VGA adapter included.	Optional Apple External Video Connector provides DB-15 mirroring, with a compatible display. Optional Apple Presentation System converts the mirrored output for television/projector or VCR use; it is not an independent extended desktop.
Speakers
Speakers	Built-in speaker; analogue and optical audio connections.	Two built-in speakers and 16-bit stereo output. Shared service specifies 22 kHz playback and 11/22 kHz recording, with ordinary audio-CD playback. Stereo input connectors are combined to mono for recording/play-through; do not treat the connector as stereo capture.
Microphones
Microphones	–	Built-in microphone for mono recording; rear microphone/line input supports PlainTalk-compatible microphones.
Keyboard and mouse
Keyboard and mouse	Apple Keyboard, Apple Mouse, USB extension cable and DVI-to-VGA adapter.	Original exact brochure and product description include a matching keyboard, mouse and necessary cables. External speakers, optional cache, Ethernet, video input/output, TV tuner and MPEG expansion are separate. Photos show the exact 5260/120 with keyboard and mouse.

Size and weight detail
Size and weight detail	The exact maker sheet labels height as 47.5 cm, width 20.6 cm and depth 51.1 cm. Earlier G5 sheets label height/depth in the opposite order; main dimensions are omitted because those published axes conflict. Maker reference weight is 20.2 kg and varies with configuration.	Exact original brochure gives 44.5 × 38.3 × 40.6 cm (height × width × depth), 20.5 kg/45 lb; current Apple support agrees on 16-inch depth and 45 lb. November 1996 Apple Facts instead gives 41.4 cm depth, with the same 20.5 kg and variation for installed devices. Shared service swaps width/depth and has inconsistent weight units. Exact original brochure measurements are retained. The shared 5260-series user manual instead lists 21.15 kg/47 lb; it agrees with the retained dimensions but not the exact brochure weight.
Power supply
Power supply	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	Exact current support gives 125 W maximum, 110–240 V AC at 50–60 Hz. Exact original brochure instead gives 240 W maximum at the same voltage and frequency; shared service gives 100–240 V 47–63 Hz, 240 W maximum and a separate 220 W all-line/load maximum. Ratings remain source-qualified; no universal operating consumption is assigned. Shared user manual agrees on 125 W maximum, with 100–240 V at 50–60 Hz.

In the box
In the box	Mac OS X Tiger and iLife ’05. Apple’s 27 April 2005 launch says these models are available “this week”; first sale is kept at April precision rather than treating the announcement as a confirmed delivery day. The older single 1.8 GHz model retained in the launch range is represented separately as Late 2004.	System 7.5.3 and 4 MB ROM in exact Apple support; original brochure calls the supplied software System 7.5. Apple records introduction on 1 October 1996. Contemporary original education ordering bundle and current November 1996 maker catalogue establish sale during 1996 but not a first-sale month; release remains year precision. Shared service explicitly identifies this model as the 120 MHz, 16 MB and AppleCD 1200i update to the 5260/100. North American Power Macintosh is kept distinct from international Performa 5260/120 and 5280 bundles.
