I'd like a wall of guns too, actually a room with all walls covered in guns, mutliple shelving units throughout stocked with guns, and of course, thousands of rounds of ammo for each and every gun.
I imagine something like a wine cellar for guns.
Long guns into padded tubes, tubes into slots and locked into place.
Small arms into padded lock boxes, same procedure.
More of a vault than a cellar but considering the value of some vintages, same difference
