MegaMacs offers the refurbished Apple Mac Pro Quad-Core 2.66GHz Xeon Workstation, model no. MB871LL/A, for $949.99 plus around $34 for shipping. That's $50 under last winter's mention and the lowest total price we've seen for this model. (For further comparison, it's also $129 under the lowest total price we could find for a used one with a smaller hard drive and less RAM.) It features an Intel Xeon W3520 2.66GHz quad-core processor, 6GB RAM, 640GB 7200 rpm hard drive, SuperDrive, NVIDIA GeForce GT 120 512MB graphics, and Gigabit Ethernet, and more. Deal ends June 26.

Note: A 30-day MegaMacs warranty applies. Also, an OS is installed, but it's not clear which version.
