The Mac Mini (marketed as Mac mini) is a small form factor desktop computer manufactured by Apple Inc. Like earlier mini-ITX PC designs, it is 7.7 inches (196 mm) square and 1.4 inches (36 mm) tall. It weighs 2.7 pounds (1 kg). Before the mid-2011 revision, all models, except the late 2009 and 2010 server models, came with an internal optical disc drive. Models pre-2010 used an external power supply and were narrower but taller at 2.0×6.5×6.5 inches (51×170×170 mm). The Mac Mini is one of three desktop computers in the current Macintosh lineup, the other two being the iMac and Mac Pro, although it generally uses components usually featured in laptops, hence its small size.
The Mac Mini was the first consumer level Macintosh desktop to ship without a display, keyboard, or mouse since Apple’s success following the release of the iMac, with Apple marketing it as BYODKM (Bring Your Own Display, Keyboard, and Mouse). The primary intended market for the Mac Mini was users switching from a traditional Windows PC to a Mac who might already own a compatible display, keyboard and mouse, though these could be easily purchased if needed. A special Server version of the computer is also intended for use as a server in a small network, and starting with the mid-2010 revision, all Server models include the Server edition of the OS X operating system.
The updated unibody Mac Mini is notable as Apple’s first computer to include an HDMI video port to connect to a television or other display, more readily positioning the unit as a home theater device alternative to the Apple TV.[7
