I used all manner of cabinets to store my boxes. The ones with deep (a couple of inches) but flat shelves work good and you can see all the boxes. The problem is, I now have to turn many up on there sides, and even then, I have not one space left in any of the flat cabinets, and not much space left in a deep drawer cabinet where I have the others. In that cabinet, they are in at ramdom, no rhyme or reason, and finding one is almost impossible now. My original cabinets have some order, although to use every square inch of space, I have had to make exceptions in some cases, merely finding a box of any caliber or country that fills a spot.
We all need to be millionaires with huge homes. I would like to have a fifty foot by fifty foot room for my library, and anohter the same size fo my cartridges and boxes, all with custom steel cabinets. When I get that, we will talk about office space and a gun room! Its going to happen, just like getting that Mercedes or BWM car I have always wanted - sure it is!! (I am still driving my 1996 Saturn, and it will probably be my last car, if I don’t run out of parts now that Saturn is closed).
Seriously, though, for a box collection that because of the way collected or the material available, will not excede several hundred boxes, Big metal cabinets like a blueprint cabinet, but with deeper drawers, work great. I have a couple of those. when you start getting three or four thousand boxes, like I think I currently have, its back to the drawing board! Unfortunately, I have no room for one more piece of furniture - my couch, easy chair, coffee table, etc. are long gone out of my hobby room, replace by four folding chairs and book cases, cabinets, safes and filing cabinets, to a point where it is hard to move! Bah humbug! Collecting is insane.
