MegaMacs offers the refurbished Apple Mac Pro Xeon Quad-Core 3GHz Workstation for $749.99 plus $2 for shipping. That's $236 under the best price we could find for a similarly configured Mac Pro (with two quad-core processors, rather than dual-core) and the lowest total price we could find. It features two Intel Xeon 5100 3.0GHz dual-core processors, 4GB RAM, 250GB 7200 rpm hard drive, SuperDrive, and Radeon X1900 XT 512MB video card. Deal ends October 16.

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