Mac mini - Computer Definition
The smallest Mac desktop computer. Housed in an 8x8" case less than 1.5 inches thick, it is a full-fledged Mac that takes up little space. Introduced in 2005 with PowerPC G4 processors, Intel-based units came out the following year. Like all desktop computers, a separate monitor, keyboard and mouse are required. For users who need a Web, mail or file server, a quad-core mini with OS X Server is also available. See Macintosh models and Macintosh.
