The Apple Store offers the factory-refurbished Apple Mac mini Intel Ivy Bridge Core i5 2.5GHz Desktop, model no. MD387LL/A, for $419 with free shipping. That's $175 under the best price we could find for a new one, although we saw a new model for $19 less in October. It includes an Intel Core i5-3210M 2.5GHz Ivy Bridge dual-core processor, 4GB RAM, 500GB hard drive, 802.11n wireless, Bluetooth, Thunderbolt port, memory card reader, HDMI, and Mac OS X (Mountain Lion). A 1-year Apple warranty applies.
