I don't know if you intend to have them in a "show" position, or just good storage. My gear is in the basement, which is very dry, year-round. I use Black and Decker plastic cupboards, for want of a better term. You assemble them, they have two doors and 5 shelves. They are not air tight, but definitely close well enough to keep dust out. They are made of molded plastic panels and such, you assemble them. Quite durable.
