Your computer's system unit has five bays that can hold up
to three 5.25-inch and two 3.5-inch drives. You can purchase
a drive to install in any empty bay.

Drive Electronics (IDE) AT interface. Your computer supports
the American National Standards Institute (ANSI) standard
for AT attachment disk drives.
It also has adapter card slots for installation of additional
expansion cards. You can install Industry Standard
