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" in the Macintosh sense means that the display is integrated in the computer case. The keyboard and mouse always remained detachable. That includes all Compact Macintoshes, the Macintosh LC 500 series and the iMac series, among others.
The Macintosh II series were the first Macintoshes designed to be placed under the monitor. Apple's most recent desktop offerings, the Mac Pro and the Mac mini, which are quite small, are meant to be set alongside the monitor.
A "tower" is a vertical case intended for placement beside the display or under a desk. This section contains both full sized towers and so-called "minitowers". Towers were first used for the high-end Macintosh Quadra models, but all later high-end Macintoshes (such as the Power Mac series) also used the tower design.
"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" 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 is the only Macintosh ever specifically designed in this way, with all of the computer models having a height of only one rack unit.

- ^ Thinner than the original iMac G5 case, with a curved back and integrated iSight camera; available with 17- and 20-inch screens.
- ^ Distinguishable from iMac G5s by its slimmer, aluminum case and aluminum border around the screen. Available in 20- and 24-inch models, both with 16:10 aspect ratio.
- ^ Thinner than the original aluminum iMac and made from an aluminum unibody. Available in 21.5- and 27-inch screens with a 16:9 aspect ratio.
- ^ The current iMac, even thinner than the unibody iMac with a screen that is fully laminated to the glass. Available in 21.5- and 27-inch screens, including "4K" and "5K" resolutions, respectively. First iMac without an optical drive.
- ^ The case is flipped on its side, creating a minitower.
- ^ The exterior shell is heavily modified, but the inside is the same.
- ^ Even though this case was introduced with the Power Macintosh 7200, Apple uses the later "Power Macintosh 7500" as the designation. This case is unofficially known as the "Outrigger".
- ^ The original Mac mini does not have an IR sensor at the side of the optical drive; also, the back connector layout was changed heavily several times
- ^ The case is modified, with the floppy drive slot moved to the bottom.
- ^ This case is a taller version of the Quadra 800 case.
- ^ This case is a shorter version of the Power Macintosh 9600 case.
- ^ Distinguished from Power Mac G5 by its twin optical drives and different arrangement of ports.
- ^ Uses a touchpad instead of a trackball.
- ^ Available in 12- and 14-inch diagonal size.
- ^ Uses an opaque keyboard and slot-in optical drive.
- ^ Available in 12-, 15- and 17-inch diagonal size.
- ^ Available in 15.4- and 17-inch diagonal size.
- ^ Available in black or white.
- ^ Available in 13.3- (MacBook, later McBook Pro), 15.4- and 17-inch (MacBook Pro) diagonal size. The 17-inch model has a fixed battery, as have the second revision 13.3-inch and 15.4 models.
- ^ Available in 12- (MacBook Retina), 13.3- and 15.4-inch (MacBook Pro) diagonal size. The MacBook has only one USB type C port, the MacBook Pro have two or four Thunderbolt 3-enabled USB-C ports. The low end 13.1-inch MacBook Pro does not have the Touch Bar.
- ^ Later models of the Xserve G4 use a slot-in CD-ROM, like the Xserve G5.
