MegaMacs offers the refurbished Apple Mac Pro Quad-Core 2.66GHz Xeon Workstation, model no. MB871LL/A, for $749.99 plus $2 for shipping. That's $80 under last week's refurb mention (which had a much smaller hard drive) and the best price we've seen for this desktop. It features an Intel Xeon W3520 2.66GHz quad-core processor, 6GB RAM, 1TB 7200 rpm hard drive, SuperDrive, NVIDIA GeForce GT 120 512MB graphics, and Gigabit Ethernet. Deal ends September 4 at 1 pm ET.

Note: A 30-day MegaMacs warranty applies. Also, an OS is installed, but it's unclear which version.
