SYSTEM CHASSIS
The chassis provides an enclosure for the system board, power supply, six PCI/ISA
expansion slots, and six storage device slots. The expansion slots include two 8-/16-bit ISA
slots, one shared PCI/ISA slot, and three 32-bit PCI slots. One PCI slot contains either a
Matrox Mystique or a Number Nine Imagine 128 Series 2 video board, depending on the
model.
The six storage device slots accommodate up to four accessible devices and two internal
hard disk drive devices. 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 slots support up to two 1-inch high 3 1/2-inch hard disks.
