>>8156613I can't recommend it because I don't have one yet, but I've been looking at Moducases. You buy them piece by piece and arrange/connect however you want them. They're aluminum with Acrylic instead of glass, and are supposedly airtight. The price is pretty high, but isn't unreasonable. People spend tens of thousands of dollars on their collections and then throw it in a $60 shelf. That's fine, but I have no problem spending a bit more to make my collection look that much better.
