The Power Macintosh 4400 (sold as the Power Macintosh 7220 in some markets) is a personal computer designed, manufactured and sold by Apple Computer from November 1996 to February 1998. It differs from prior desktop Macintosh models in that it was built with off-the-shelf components including an IDE hard drive and an ATX-style power supply. The 4400 replaced the Power Macintosh 7200, the final remaining PowerPC 601-based system in Apple's lineup.
The 4400 was introduced to the market at a time when several Macintosh clones competed with its computers on price. The "Tanzania" logic board in the 4400 was an Apple design but had only been used in clone system. MacWEEK's review described the case as "Strange in the Apple brood; when compared with PCs it fits right in with the flock. It is contained in a stock desktop PC case fitted with Apple's distinctive curved nose piece. The back is industrial-looking, while bent sheet metal fills the case's insides, sharp edges and all. The IDE drive sits on end, while the Comm II slot (occupied with an Ethernet card) and two PCI slots reside in a riser card. For the first time, Apple has abandoned automatic switching in the power supply, a small cost savings at the expense of international users' convenience".
This was the only Power Macintosh to be designed with the goal of using low-cost manufacturing techniques; the 4400 was removed from Apple's lineup a few months after the Power Macintosh G3 went on sale, which was priced comparably to the 4400 but used Apple's Outrigger form factor.
