The fifth-generation lineup, featuring Apple Silicon, was introduced in November 2020 in the original silver style. This model also has solid-state storage and replaces most of the data ports with USB-C sockets. The 2018 fourth-generation Mac Mini model has Thunderbolt, an Intel Core i5 or i7 CPU, and also changed the case's default silver for space gray. The third-generation, which was unveiled in June 2010, had a thinner, unibody aluminum case and an HDMI port, and was more readily positioned as a home theater device and an alternative to the Apple TV. It featured more advanced components and internal software updates, and it switched the CPU to the Intel Core Solo. In February 2006, Apple announced the second-generation lineup. In January 2005, the original Mac Mini was introduced with the PowerPC G4 CPU. The machine was initially branded as 'BYODKM' (Bring Your Own Display, Keyboard, and Mouse) as a strategic pitch to encourage users to switch from PCs running operating systems such as Microsoft Windows and Linux. Since launch, it has shipped without a display, keyboard, and mouse.
