The Mac mini is the smallest desktop computer made by Apple Inc. Two models were released in the U.S. on January 22, 2005 (January 29 worldwide); updated versions were released on July 26 2005. Models with Intel Core processors were released on February 28 2006, with slightly revised models introduced on September 6 2006. On August 7 2007, new models were released with Intel Core 2 processors with 1.83 or 2.0 GHz speeds.

The mini, which resembles earlier Mini-ITX PC designs, is quite small for a desktop computer: 6.5 inches (16.5 cm) wide, 6.5 inches (16.5 cm) deep, and 2 inches (5.1 cm) tall. It weighs 2.9 pounds (1.31 kg); an external power supply is roughly half the size of the computer.
