This was my first display case. Made by GEMO. It's still a very nice case, cleverly constructed and really keeps the dust out. However, it's a little bit small and was relatively expensive.
After I filled up my first case, I build the display case below. The clear parts on the sides as well as the door are made from clear acrylic sheet. The shelves are glass. Not cheap either, but it came out well and hold a lot of models.
This is the label I had for most of my models. I used an Excel table to list all the pertinent info about my models, then used the Word merge function to create these labels. I've since come to the realization that these labels are just too big and block out too much space in my display case.
