This chassis has three 5.25-inch and one 3.5-inch drive bays.

The top 5.25-inch drive bay will be occupied by the CD-ROM drive. The lower two may be occupied by optional devices such as tape drives. Unoccupied bays will be covered by a metal EMI shield that must be removed before installing a device into that bay.
