The Apple Store offers the factory-refurbished Apple Mac mini Intel Core i7 Quad 2.3GHz Server, model no. MD389LL/A, for $849 with free shipping. That's tied with last week's mention and $100 under the lowest total price we could find for a new one. It features an Intel Core Ivy Bridge i7-3615QM 2.3GHz quad-core processor, 4GB RAM, two 1TB hard drives, 802.11n wireless, Bluetooth 4.0, and Mac OS X Server. It has no optical drive. A 1-year Apple warranty applies.
