Apple Power Mac G5 The Apple Power Macintosh G5/1.8 (PCI), uses a lower cost motherboard based on the one used in the iMac G5 with a 600 MHz (3:1) system bus. This model features a 1.8 GHz PowerPC 970fx (G5) processor with an optimized AltiVec "Velocity Engine" vector processing unit and 512k level 2 on-chip cache. It shipped configured with 256 MB of 400 MHz PC3200 DDR SDRAM, an 80.0 GB (7200 RPM) Serial ATA hard drive, an 8X DVD-R/CD-RW "SuperDrive", and a NVIDIA GeForce FX 5200 Ultra (AGP 8X Pro) video card with 64 MB of DDR SDRAM.

Connectivity includes USB 2.0, FireWire "400" and "800", ADC, DVI (single link), optical digital audio in/out, and support for AirPort Extreme (802.11g) and Bluetooth 1.1. This model does not support PCI-X.

Like the earlier models, the Power Macintosh G5/1.8 (PCI) uses the same "anodized aluminum alloy" case divided into four different thermal zones with nine computer-controlled fans for optimum cooling, and features a removable side panel for easy access to internal components. Custom configurations also were available.
