List of Macintosh models by case type
This list of Macintosh models by case type contains all case designs used by Apple Inc. for its Macintosh computers. The list is sectioned by general case layout, but inside the sections the order is chronological. Models that used multiple names (like most Performas) are listed only once. Where available, the "form factor" from Apple's datasheets has been used to determine the case designation and the computers that used it. For all-in-one models and notebooks that have the same basic case design, but differ in size, just one type is  listed. Also, some models that differ only slightly or internally are listed together, like the two iMac G3s and the Power Mac G4s. All-in-one. "All-in-one" in the Macintosh sense means that the display is integrated in the computer case. The keyboard and mouse always remained detachable. Desktop. The Macintosh II series were the first Macintoshes designed to be placed under the monitor. Apple's most recent desktop offering, the Mac mini, is meant to be set alongside the monitor. Portable. "Portable" in this case means computers that are able to run on internal batteries - modern computers  like the Mac mini are arguably more portable than the "luggable" Macintosh Portable, but have no integrated batteries. All modern portable Macintoshes use the notebook design, which the PowerBook series helped to establish. Rackmount. "Rackmount" computers use cases that are designed to be screwed into a standard 19-inch rack, a form factor that is mostly used for servers. The Xserve series and Rackmount-configured Mac Pro (3rd generation) are the only Macintosh models ever specifically designed in this way. They can have wheels, and be racks or towers.
