The smallest Mac desktop computer, the Mac mini weighs less than three pounds and comes in a 7.7" square case only 1.4" thick. 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, which can be from Apple or other companies.
The 2020 mini offers up to 64GB RAM, 2TB solid state storage and six 3.2 GHz processing cores. See Macintosh models

The Mini's Predecessor
