Have a DELL Inspiron 660 , the layout of the Hard drive caddy makes it hard to add additional drives.
Screenshots are shown below. Suggestion of another easy and inexpensive alternative. Thanks.

Answer #1
I would screw the side of the hard drive to the front (inside) of the case. I done it many times to a few case that have no more room for anymore hard drive/accessories.
of course it’s not “really” the right way but it last me for many years and save me ton of space. Of course is free also which is a plus.
