It is utterly vile to keep such beautiful figures hidden in a box when not in play.
The stuff in boxes is all unpainted long term raw material. Everything that is painted is in display cabinets. The photo a few posts above is the next display cabinet for my Napoleonic collection. For now those are stored on the main table in my primary gaming room. They will get transported over to the Napoleonic display gallery once construction in that gallery room is completed.
The rest of my collection is also housed in display cabinets. My main gaming room has two walls covered in custom cabinets for that purpose:
Army Storage: Three cabinets with two adjustable columns each. These hold display trays 24" wide and 18" deep with up to 10 shelves stackable. Below you can see a quick photo of the "Small scale" cabinet. Mostly 6mm Epic with some Dystopian Wars at the bottom.

Skirmish Storage: Three cabinets with five shelves of 36" x 12". Each shelf has a custom "half-shelf" to elevate the rear area. The first cabinet holds (from top) Blood Bowl, Mordheim, Battlefleet Gothic.

The second cabinet holds 15mm DBA, Saga, Man-o-War plus some empty space for the future


The third cabinet holds Warcry, Blackstone Fortress, Warmaster, and a 28mm Early Imperial Roman force at the bottom.

Bottom line, nothing painted is dishonoured by box storage

Editing to add something a bit more Napoleonic. I mentioned the table that currently stores the Napoleonic project. Here it is in a crappy photo. You can see the finished units, labelled bases for the unfinished ones, and the flag sheets for the Prussians in the foreground. In the back you can see the three army cabinets.

For the curious (and my amusement), I added a labelled version of the photo.

Apologies for the bad photo quality. I made a few attempts and there is no hope to focus over this depth/lighting situation with my phone. The table is 9' long...
