MegaMacs offers the refurbished Apple Mac Pro Intel Xeon 8-Core 2.4GHz Workstation, model no. MC561LL/A, for $2,199.99 plus $48.66 for shipping. That's the lowest total price we've seen for this model with 12GB RAM, although we saw it for $319 less (with only 8GB RAM) in October. It features two Intel Xeon 2.4GHz quad-core processors (eight cores total), 12GB RAM, 1TB 7200 rpm hard drive, SuperDrive, and OS X 10.9 Mavericks.
Note that no warranty information is provided. Note that this is a "special order item" and will incur a shipping delay of unspecified length.
