Anyone have any good ideas for storage of 3.5" internal hard drives?

I have a few of the Styrofoam packs that Newegg receives, and then ships, large orders in, but I was looking for something a little more polished to store 20-30 external hard drives in.

Currently using something similar to this:




But would love a more refined storage solution.

Ideas?

 

Hmm, Is that standard Styrofoam or the anti-static type? I think I've usually seen hard drives stored in an anti-static bag when used with foam like that.

 

I use A/S bags before placing the drives in the foam.
