Power Macintosh G4 Cube

In 2000, Apple introduced one of its most distinctive designs ever: the Power Mac G4 Cube. "Cube," for short, was one of the more beloved and bedeviled Macs ever made. It had a huge following among many Mac fans but was plagued by faint lines on the exterior that some felt were cracks and others felt were blemishes. Apple discontinued the Cube in 2001 after noting that buyers seemed to prefer the slightly cheaper Power Mac G4 minitower.
