The introduction of the Desktop and Mini Tower models coincided with Apple starting to sell build-to-order Macs directly from its web site in an online store, which was unusual for the time as Dell was the only major computer manufacturer doing this. It represented Apple's first step towards eliminating redundancy and complexity in the product line by replacing eight Power Macintosh models (and the Twentieth Anniversary Macintosh) with three: Desktop and Mini Tower models for professional and home use, and an All-In-One model for education. The Power Macintosh G3 (also sold with additional software as the Macintosh Server G3) is a series of personal computers designed, manufactured, and sold by Apple Computer, Inc.
