At long last, Apple's new, incredibly small Mac Pro is going on sale. From December 19 you'll be able to pick up an entry-level Mac Pro for $3000 (quad-core). The mid-range six-core model will set you back $4000. Pricing for the eight- and 12-core systems is not yet available, but a fully maxed out system -- with two FirePro graphics cards and 1TB of solid-state storage -- is expected to cost around $10,000.
