Expercom offers the Apple Mac Pro Intel Xeon 8-Core 2.4GHz Workstation, model no. MC561LL/A, for $2,099 plus $27.50 for shipping. That's tied with our mention from two weeks ago and $523 under the lowest total price we could find for a refurb direct from Apple (this one's new). It features two Intel Xeon 5100 2.4GHz quad-core processors (8 cores total), 6GB RAM, 1TB 7200 rpm hard drive, SuperDrive, ATI Radeon HD 5770 1GB video card, and Mac OS X 10.7 Lion.
Of note, scroll down and add three years of AppleCare for an additional $100. That's also tied with last week's mention, and the lowest total price we could find by $19
