ExperCom continues to offer the refurbished Apple Mac Pro Intel Xeon 12-Core 2.4GHz Desktop PC (no monitor), model no. MD771LL/A, for $2,799 plus $29 for shipping. (It's the bottom option.) That's $288 under the lowest total price we could find for a new unit elsewhere, although we saw it for $29 less last week. It features dual Intel Xenon E5645 2.4GHz Westmere hexa-core processors (12 cores total), 12GB RAM, 1TB hard drive, SuperDrive, Radeon HD 5770 1GB graphics, 802.11n wireless, Bluetooth 2.1+EDR, and Mac OS X 10.7 Lion. Deal ends September 9.

A 90-day ExperCom warranty applies.
