Thanks, I was originally looking for something small and not furniture-like. Maybe something more closely related to a baseball/football display case? I found a couple of places with the baseball cases and such for a decent price but then I started thinking...why not put all of my puzzles in a case? Well, buying individual baseball cases was out of the question then, as I have upwards of 80 puzzles.
So I looked through the link you just posted with the cabinets and found a couple there and also at a place called Gemo Displays >
http://www.gemodisplays.com/512-3212.html < is one I liked. This way I could put what I have in here and still have room to grow!

unfortunately this thing is quite expensive! So it will be quite a while before I can afford to get anything like this, unless I find one in a garage sale or something
I would still like some smaller cases for individual puzzles in the meantime, so if anyone finds any, please let me know! Something large enough to fit a Golden Cube, I assume it's the largest, or maybe a Pyraminx Crystal might be bigger? I dunno...
Also, I've wondered about the stand on the inside of the case to hold the puzzle in place...at first I thought about cutting pieces of acrylic to fit the shape/angle of the puzzle, then I thought about just hotgluing a rubik's stand to the bottom of the case. What are your thoughts?
