The 6400 replaced the Performa 6360 and used a new tower configuration. It was available in 180 MHz and 200 MHz configurations. The neatest feature: a built-in subwoofer for very rich sound.

The 6400 was replaced by the Power Mac 6500 . The Performa/Power Mac 5400 is virtually identical to the 6400 – but with a built in monitor.
