Contemporary Macworld reporting of Apple Store configurations also documents dual 1.25 GHz processors, each with 2 MB L3; this custom build is labelled in configuration details rather than presented as a second stock base.	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.
GPU
GPU	Stock ATI Radeon 9000 Pro with 64 MB DDR in an AGP 4x slot. Macworld also documents a custom dual-processor build with NVIDIA GeForce4 Titanium; that build has other upgrades and is not treated as a freely interchangeable stock configuration.	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.
Memory type
Memory type	Stock 256 MB PC2700 DDR333; four DIMM slots, maximum 2 GB. The single-processor configurations retain the stock drive and graphics at base and maximum memory. The documented dual-processor custom base has 256 MB.	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.
Storage type
Storage type	Stock 80 GB 7200 rpm Ultra ATA/100 hard drive; up to four internal drives. Tray-loading Combo drive reads DVD at 8x and CD at 32x, writes CD-R at 16x and CD-RW at 10x. Macworld documents a dual 1.25 GHz custom base with 80 GB, Combo drive and Radeon 9000 Pro, and a separate upgraded build with 2 GB RAM, two 160 GB drives, SuperDrive and GeForce4 Titanium. The two-drive build is described here without flattening its drives into a single capacity.	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.

Size and weight detail
Size and weight detail	Maker dimensions: height 43.2 cm, width 22.6 cm, depth 46.7 cm; weight 19.1 kg. These published metric values differ slightly from the FW800 sheet.	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.
Power supply
Power supply	–	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.

In the box
In the box	Mac OS X 10.2.4 and bootable Mac OS 9.2.2, install/restore DVD and Apple Hardware Test. First sale uses the 23 June 2003 Macworld report that these models were for sale at Apple’s online store; a 29 June report quotes an Apple spokesman confirming manufacture and sale. The first day is contemporary Apple Store reporting rather than a retained maker launch notice.	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.
