Was the Power Mac G4 Cube the first “cube” Apple system?
For all practical purposes, the Power Macintosh G4 Cube was the first and only “cube” system released by Apple. Depending on how precise you would like to be (as the Power Macintosh G4 Cube is 2.1 inches taller than it is wide or deep), you could argue that that Apple never has released a cube. You alternately could choose to argue that the clear plastic portion of the bottom of the case “doesn’t count” and therefore it is more-or-less a cube. However, the subsequently released Mac mini is a “cuboid” shape, and before Apple purchased the company, NeXT released the cube-shaped NeXTcube. The NeXTcube was generally regarded as a failure, but was said to be before its time. One Mac clone maker — MaxxBoxx of Germany — also released a series of large cube-shaped Mac clones.
