I actually thought of going to a woodworker (not sure if that's the right way to call them, excuse my lack of english knowledge lol).

I guess I will need a special wood or coating. I'm not sure if it's better to have a wood that "drinks" or not. since it's gonna be between 40-60% humidity (that's what I've been told would be the target), I not sure if all woods react the same.

So maybe I'll make them "build" me one from scratch. I'll definively use those wall stand Eggman. I have a straight one but I'll need those curved one. I don't want to have a Wall-wide cabinet lol

Since I'll have a cabinet I think I'll make it lockable for security. What the heck!

I could go overboard and make it so it keeps the inside at a temperature between 14 and 24 Celsius but I'm not too sure about heating system in a wooden box if you know what I mean....
