Humid weather and dry storage

With the humid summer knocking on spring's door, I've been thinking about how to store my equipment safely to prevent damage from moisture and fungus.  Especially since my apartment will not be air conditioned the entire summer I expect it to be a little more humid inside than past summers.

I've got some rechargeable Silica Gel Desiccants Packetsin my camera case that are several years old and am considering buying some more.  I've also been considering getting a larger sealed storage box.  In Japan, many of the larger camera shops sell these sealed dry storage cases to fight the humidity and prevent damage during the wet and humid months.
