Need a factory made storage racks for 2.5" and 3.5" disk drives. Prefer those which come with good quality PC chassis. Should have lock/slide-IN/Out if possible.
DIY if you can procure the materials. Its a PITA for me living on the far side. Can't even find a freaking acrylic sheet. No one willing to ship 'em here. Else I would've done it myself.
