Installing a 5.25-Inch Drive on a Minitower (top) and Desktop (bottom)
5. Install the drive in the desired drive bay by sliding it into the front 
of the drive cage 2; the drivelock automatically secures the drive 
in the bay.
Ä
CAUTION: The bottom 5.25-inch drive bay has a shorter depth than the 
upper two bays. The bottom bay supports a drive that is no more than 17 
cm (6.7 inches) in depth, including the cables that attach to the back of 
the drive. Do not try to force a larger drive, such as an optical drive, into 
the bottom bay. This could cause damage to the drive and the system 
board. 
The use of unnecessary force when installing any drive into the drive bay 
may result in damage to the drive.
