Optical/Floppy Drive Installation
As we have shown, this case has four 5.25” bays and you can transform one of them (the lower one) into a 3.5” bay (which is the default configuration).
Optical drives must be installed using a sliding mechanism. On the bottom of the case you can find six rails to be attached to optical drives, see Figures 31, 32 and 33.
Installation is simple: screw two rails to each optical drive (using thin thread screws) and then simply slide the unit into the bay until you hear a loud click.
On Figures 36 and 37 you can see the floppy disk drive drawer. If you want to use this bay as a 5.25” simply unscrew the two rails present on the drawer and screw them on your optical drive.
