The Apple Macintosh IIsi features a 20 MHz 68030 processor, 2 MB or 5 MB of RAM, and a 40 MB, 80 MB, or 160 MB hard drive in a compact, easy-to-expand desktop case.

Basically, the Macintosh IIsi is a scaled-down version of the Macintosh IIci, in a smaller, sleeker case with fewer expansion options. However, the Macintosh IIsi was also the first Mac to support built-in audio recording capabilities, an option that the IIci lacks.
