Build it, you're a builder!
Exactly!
All my stuff is dioramas, don't have anything just sittin' there... I just screw brackets to the wall and hang shelves on them... Got a couple bookcase types as well.. I don't have the room for or the inclination to buy any enclosed cases... Frankly, you can't see anything in a curio-type cabinet, my wife has one in the living room and noone who visits ever comments on the stuff she has in there (quite a lot of cool stuff, if ya ask me)... But my dios always get noticed and commented on (I manage an apartment building and tennants are always coming over for one thing or another, so I get a pretty good cross-section of folks.)...
They get dusty, but I make a regular ritual out dusting them once a week or so. Models with pastel weathering get a little screwed up, but five minutes with the pastel brush fixes it fast... I also keep a can of compressed air and a keyboard vac handy..
Only a select few of my dios last any significant amount of time... After six-twelve months, they get torn down and the models get sent to the "salvage yard" if I haven't sod them or put them on display somewhere else... I get sick of looking at them, ya know? Now that I've finally gone digital, it's better for me to photograph them and then I don't need to worry about storing/displaying them... Some also simply get boxed up and placed under my back bench in the War Room.. There they remain until they're salvaged or rebuilt as a new one...
The dioramas that I'll keep on disply indefinately are my (all are WIPs right now, but the space is available) 1/48th B-29, B-17, and B-24 dioramas, along with my Mauldin and shadow-box dios.
If I still had my Ex-House (3rd Ex got it) it'd be a different story... There, after I finished it and built my War Room down there, I had the basement walls shelved from floor to ceiling with 18" deep lighted shelves that ran the whole 22 feet of South wall and 16 feet of the East one... Had room for dozens of average-size dioramas... Even had power to each shelf run for individual lighting... *Sniff*
Maybe after I win the Powerball this weekend I'll build a house AROUND my War Room...
