The IIvx was aimed directly at the mid-range market. It introduced a new case design (the first case built with an internal CD-ROM in mind), and ran on a 32 MHz 68030 processor with a 68882 FPU. However, the 16 MHz bus made it roughly equivalent to a 25 MHz IIci. The IIvx cost $2,950.

The Mac IIvx began its life in development as a proof-of-concept to
see how an internal CD-ROM drive could be added to a Mac -- but
after John Sculley's speech at MacWorld Tokyo promised a Mac with a
CD-ROM drive (and surprised the development team), the IIvx was
rushed into production, with a lot of shortcuts taken in its
design. Its 32 MHz processor was crippled by its 16 MHz bus (making
it slightly slower than the IIci), and its serial port was limited
to 57.6 kbps (which could cause problems with serial connections and
MIDI hardware). The final nail was driven into its coffin when the
much-more-powerful Centris 610 was released four months later for
the same price. Since then, people who buy an expensive Mac which
quickly becomes obsolete are said to be "IIvx'ed". Interestingly,
the IIvx was also the first Mac to have a metal case.
