Storing 3.5″ hard drives in a Pelican case

Pelican 1525 Air can store 32 hard drives.

I was looking for a watertight case to store a bunch of 3.5″ hard drives.  The idea was to protect the off-line backups from water damge in case sprinklers get activated in the building.  It was decided that water or dust damage was a more likely threat than fire, so the solution did not have to be fire safe.
