I purchased a ”dual-dual” (”quad”) Mac Pro G5 with two 970MP processors, 8 GB of ECC RAM, PCI Express system bus, and two SATA HDDs in November 2005 (?). Contrary to what many will tell you this machine was not water-cooled: that was the previous generation of G5s, which had multiple single-core processor chips clocked at higher frequency. This machine is air-cooled and varies between sounding like a thundering highway tuck and a jetliner on takeoff.

With a pair of CinemaDisplay 24” (?) it served as my main workstation well into 2009, and was a truly awesome machine and I keep it in working condition with OS X 10.7 for the purposes of nostalgia. It was by far the most performant-compared-to-prevailing-average machine I have ever owned (back at a time when such comparisons mattered).
