hard disk drive stack rack

hard disk drive stack
you will need 4pcs thumbscrew for each hard drive

how to align
loosely screw 2 drives on each other... tighten while on top of each other
3rd hard drive.. you can just tighten on an aligned drive.

2 files available.. in my experience 500gb and below use short and 1gb above use extended..
they are just 1.5mm difference.. if not sure use extended
