Apple Mac Pro G5 1.1 running Mac OSX 10.6.8, Processor 2 x 2.66 GHz Dual Core Intel Xeon, Memory 3 GB 667 MHz DDR2-DIMM. Comes with 2 Apple Cinema displays, 20" 1680x1050, and several external hard drives and an external Superdrive. Great condition, just reset to factory, was running Final Cut Pro and Logic. Only known issue is extra USB ports don't seem to be working on one display, display itself works/connects fine.
