History: The PowerMac G4 Cube introduced a dramatic new case design. Housed in an 8x8x8 cube, the G4 Cube combined the elegance of the iMac with the power of the PowerMac G4. The Cube traded expandability for its diminutive size: There were no PCI slots, and while the Graphics was fit into an 2x AGP slot, there wasn't room for full-length AGP cards. With the exception of PCI expansion, the Cube was as versatile as it's larger G4 cousin: Three RAM slots, an AirPort slot, and two USB and FireWire ports. One gripe many people had with the Cube was its lack of conventional audio input and output. Instead, it came with an external USB amplifier and a set of Harman-Kardon speakers. Shortcomings aside, the Cube was a remarkable feat of engineering, crammed inside an elegant case. The Cube was not nearly the success that Apple had hoped it would be. The consensus was that Apple had misjudged the market, making the Cube an expensive "luxury" computer instead of a cheaper monitor-less iMac.
