The Apple Store offers its factory-refurbished Apple Mac mini Intel Core i5 2.5GHz Desktop (pictured), model no. MC816LL/A, for $549 with free shipping. That's tied with our mention of a refurb from two weeks ago and a buck under the lowest total price we could find for a new unit today. It features an Intel Core i5-2520M 2.5GHz Sandy Bridge dual-core processor, 4GB RAM, 500GB hard drive, AMD Radeon HD 6630M 256MB graphics, 802.11n wireless, Gigabit Ethernet, Bluetooth 4.0, SDXC card slot, Thunderbolt, and Mac OS X 10.7 Lion.

Also available is the factory-refurbsihed Apple Mac mini Intel Core i7 Quad 2GHz Server, model no. MC936LL/A, for $759 with free shipping. That's $240 off and ties our refurb mention from two weeks ago as the lowest total price we could find. This Mac mini features an Intel Core i7 2GHz Sandy Bridge quad-core processor, 4GB RAM, dual 500GB 7200 rpm hard drives, 802.11n wireless, Gigabit Ethernet, and OS X 10.7 Lion Server.
