The Power Macintosh 4400 (also known as the Power Macintosh 7220 in some markets) is a mid-to-high-end Macintoshpersonal computer designed, manufactured and sold by Apple Computer from 1996 until 1998. The Power Macintosh 4400 was rather different from most other Macintosh models, in that the floppy disk drive is on the left rather than right, and like the Centris 650, the casing is made of metal rather than plastic. Apple did this to reduce production costs, in addition to using more industry standard components such as an IDE hard drive and an ATX power supply.
It was also available in a PC compatible system with a 166 MHz DOS card containing 16 MB of RAM and a Cyrix 6x86 processor. The first 4400 model was only sold to the Europe market, an updated 200 MHz 603e model was released in the United States in February 1997 as the Power Macintosh 4400.
The Power Macintosh 4400 is known as the Power Macintosh 7220 in Australia and Asia, where the number 4 is considered unlucky.
