The Apple Macintosh Performa 400 features a 16 MHz 68030 processor, 4 MB of RAM, 512k of VRAM, and an 80 MB hard drive in a compact, easy-to-upgrade "pizza box" case.

The educational version of the Performa 400 is the LC II.

Please note that the picture is an LC 475/Performa 475 and the Performa 400 design is similar, but has a "flatter" front with a groove rather than a sleek curve. EveryMac.com eventually will swap out this photo with a more precise one.
