Do you have the original packaging?
Heat build up as stated above is very harsh. Better the storage room you mentioned IMHO. It's better to pack them when the humidy is low. You can use dessicant packets (the ones that come inside the electronics boxes use silica as absorbent) to trap and keep humidity low inside the plastic bags you are going to use. The storage room ideally should not be too humid since humidity destroys cartons. I this is the case at least keep some distance from walls and floor and also plastic wrap the external cartons to help them stay in good condition. Hope this helps
