Using the Correct Drive Bay
Your computer contains nine bays that allow you to install
various drive types in the following configurations:
Three externally-accessible bays for mounting half-height
3.5-inch or 5.25-inch drives that use removable media. The
system comes with a 3.5-inch diskette drive installed in the
top external bay.
Four lower internal bays for mounting either four
half-height or two full-height 3.5-inch SCSI drives.
Two upper internal bays for mounting either two
half-height or one full-height 3.5-inch IDE hard disk drives.
You can also mount two half-height or one full-height
3.5-inch SCSI drives in these bays.
