Displaying the Collection

So, long story short, I have approximately 70% of all models in series 1 to Final Evolution; I'm planning to search for, and acquire the missing ones in order to have a full 1st, Mystica, 2nd, Atomic, 3rd, Mythos, Energheia and Final Evolution collection, and I'll need a decent way to display it in my room.

The issue is: I cannot use any shelving/ground touching-glass cabinet, as my room is too small, But I have some space on my walls; I was thinking to look for a wall showcase, but they look sorta small, and I think something would have to be left out… Do any of you guys have any suggestions or interesting links?

Do y'all think there's a way to display all of them in one case or two, or am I better off *shelving* (heh) the idea and keep them in boxes inside my wardrobe?
