MegaMacs offers the refurbished Apple Mac mini Intel Core 2 Duo 1.83GHz Desktop, model no. MB138LL/A, for $229.99 plus $2 for shipping. That's tied with last week's mention and $278 under the lowest total price we could find for a similarly configured used unit elsewhere. It features an Intel Core Duo 1.83GHz dual-core processor, 2GB RAM, 80GB hard drive, DVD burner, AirPort Extreme (802.11g wireless), Bluetooth, and Mac OS X 10.7 Lion. Deal ends September 4.

A 30-day MegaMacs warranty applies.
