Adding hard drive with no place to mount

[Morph]

What do you guys do if you want to add another hard drive and there's no spots left to mount it? There's enough space in the case, if I could find an add-on hard drive cage I could probably mount it somewhere inside. Is there any place where I can buy an add-on cage or some kind of mounting hardware?

I know people that have run slim pieces of metal down from where their last hdd ends. They put the screws that go into the HDD through these pieces of metal, thus they have 4 pieces hanging down, on the ends there are holes for the harddrive and they screw it in.

I know people that just lay them inside their case too

either way works, or you could buy an HDD cage.
