The Macintosh IIvx (code name Brazil) is the last of the Macintosh II series of Macintosh computers from Apple Computer. The IIvx included either a 40, 80, 160 or 400 MB hard drive, three NuBus slots, and a Processor Direct Slot. It was the first Macintosh to have a metal case and the first case design of any personal computer to provide for an internal CD-ROM drive. An internal double-speed CD-ROM drive which used a disc caddy was available as an option from Apple.
