I have just been given an ultimatum......."Get your camera "JUNK" out of my living space or it goes out the door". Yikes.

Granted, there seems to be an ever growing amount of photo gear that has accumulated over the years but "JUNK" was a hard pill to swallow. I have become a bit of a receptacle bin for peoples unwanted cameras.
How can I safely stow cameras and lenses? Would those large plastic storage containers be ok? I"m talking about old rangefinders and leather cases as well as a bunch of 35mm slr,s.
