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 seven storage device
slots. The expansion slots include three 8-/16-bit ISA slots, one shared PCI/ISA slot, and
one 32-bit PCI slot. For network-ready configurations, one slot has a network board
installed and the remaining slots are open.
The seven storage device slots accommodate up to four accessible devices and three
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 three 3 1/2-inch hard disks; one in the standard front
slot. The other two install into a drive bracket that ships with the system. The bracket
attaches to the inside rear of the system.
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 and two internal slots available for optional devices. The multimedia systems ship with
an accessible 3 1/2-inch diskette drive, an internal 3 1/2-inch hard disk drive, and an
accessible 5 1/4-inch CD-ROM reader, leaving two accessible 5 1/4-inch storage device
slots and two internal slots available for optional devices.
Figure 1-2 shows the front panel features and the locations of the accessible storage devices
in a minitower system. Multimedia systems come with a CD-ROM reader installed in the
top accessible device slot.
