MINITOWER SYSTEM CHASSIS

The minitower chassis provides an enclosure for the system board, power supply, five
useable expansion slots, a six-connector PCI/ISA backboard, and five storage device slots.
The expansion slots include three 8-/16-bit ISA slots, one shared PCI/ISA slot, and one 32-

A video board (the Matrox Millennium™ board described in "Graphics Subsystem")
occupies one of the expansion slots to provide graphics and/or video functionality.
The five storage device slots accommodate up to four accessible devices and one internal
hard disk drive device. The accessible devices include the standard one-inch high 3 1/2-inch
1.44-MB diskette drive and up to three 1.6-inch high 5 1/4-inch storage devices. The
internal device slot supports the standard 1-inch by 3 1/2-inch hard disk.
The non-multimedia hard disk systems ship with an accessible 3 1/2-inch diskette drive and
an internal 3 1/2-inch hard disk drive, leaving three accessible 5 1/4-inch storage device
slots available for optional devices. The multimedia systems ship with an accessible 3 1/2-
