CPU
CPU	Two physical PowerPC G5 processors at 1.8, 2 or 2.5 GHz, each with 512 KB L2 cache. Per-processor front-side bus is 900 MHz, 1 GHz or 1.25 GHz respectively. Only the dual 2.5 GHz uses the maker’s liquid-cooling system.	100 MHz PowerPC 601 with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 33.3 MHz system bus; 4 MB ROM
GPU
GPU	Dual 1.8 and 2 GHz: NVIDIA GeForce FX 5200 Ultra with 64 MB DDR. Dual 2.5 GHz: ATI Radeon 9600 XT with 128 MB DDR. Optional ATI Radeon 9800 XT with 256 MB occupies the adjacent PCI slot as well as AGP.	Power Macintosh video card with 2 MB VRAM, expandable to 4 MB using four 512 KB SIMMs; separate built-in DRAM video uses system memory. This is the non-AV model, without the AV card's S-video connections.
Memory type
Memory type	DDR400 PC3200 in matched pairs. Dual 1.8 GHz starts with 256 MB and has four DIMM slots with a 4 GB maximum. Dual 2 and 2.5 GHz start with 512 MB and have eight slots with an 8 GB maximum. Base and maximum memory rows retain each model’s stock storage and graphics.	Apple's Japanese bundle has 16 MB including 8 MB soldered to the logic board; eight 72-pin noncomposite 80 ns SIMM sockets accept matched pairs, up to 264 MB total. Apple Service Source also lists an 8 MB configuration.
Storage type
Storage type	Stock 80 GB on dual 1.8 GHz and 160 GB on dual 2/2.5 GHz; 7200 rpm Serial ATA. Two bays with 150 MB/s interfaces; optional 80, 160 or 250 GB drives, up to two 250 GB drives. One optical bay with 8x DVD-R SuperDrive; Combo drive is optional.	Japanese bundle has a 700 MB internal SCSI hard drive, 1.44 MB floppy and internal 2× AppleCD 300i Plus CD-ROM. The exact-model service table also lists a 1 GB hard-drive option; CD-ROM inclusion varies by configuration.
Expansion slots
Expansion slots	AGP 8x Pro graphics slot. Dual 1.8 GHz has three 64-bit 33 MHz PCI slots. Dual 2 and 2.5 GHz have PCI-X: two 100 MHz and one 133 MHz slots.	Three NuBus slots and one processor-direct slot occupied by the video card; fitting an optional AV card replaces that video card rather than adding another card alongside it
