To install hard disk drives in the cage you need to first install two metallic rails to each drive. These rails are located inside a small toolbox located below the hard disk drive cage.

The installation of optical drives, floppy disk drives and a hard disk on the 3 ½” internal bay located outside the hard disk drive cage is very easy. First remove the cover located in front of the bay you want to use (step not necessary for installing the hard disk drive), remove the screwless installation mechanism twisting its knob counter clockwise, slide the drive in the bay, place the plastic installation mechanism back in place and then turn its knob clockwise. That’s it.
