The Apple Macintosh IIx features a 16 MHz 68030 processor, a 68882 FPU, 1 MB or 4 MB of RAM, a 40 MB or an 80 MB hard drive, and the option of an Apple Macintosh II video card in an easy-to-expand desktop case.

The Macintosh IIx uses the same "Open Mac" case as the Macintosh II, but shipped standard with a faster processor and a faster FPU -- it was the first Mac to ship with the 68030 processor and the 68882 FPU -- as well as dual 1.44 MB disk drives. It also requires significantly less "tinkering" to upgrade the RAM and other internal components.
