Yo Troopers, had this one before, so in case you missed it will give my version. I just had a look at all the links you guys put up for cabinets, and to be honest they are totally unsuitable and way overpriced IE: narrow shelves narrow cabinets could hardly get a Troop in them never mind a Regiment lol. The best and cheapest way is to go to a second hand furniture sales or auction rooms, and look out for an old wardrobe BUT it MUST have panel doors. Most of the old type of wardrobes have fancy panel doors, so if they are knocked around a bit they usually go cheap. I had a Mahogany Hall Wardrobe 5 feet high x 20 inches wide been in the family for years, took the panels out of the doors, removed all the coat rails and coat hooks, put a light in. Then went and bought 3 plate glass shelves and metal shelf holders had to drill them in the sides. NOW guys the MOST important bit, if you have young ones YOU MUST GET LAMINATED GLASS FOR THE DOORS, its heavier but wont break. This is the honest truth, had the cabinet two weeks and my little Trooper slipped and went head first into the cabinet butted it good style, the only outcome thank God was a big bruise on his forehead. Also bought a couple of cabinet locks you only need a 1/2" drill easy to fit and the cabinet is secure from those little fingers. My little fella is always trying to get in, its like a magnet for kids when they see the Toy Soldiers. Just to add I also have two full size Wardrobes 6' 5" high x 4' wide that could be converted so would suit you dio guys down to the ground.
PS. forgot to add while you are at it put mirrors in the back, I forgot to do it at the time, had to empty the cabinet out then put mirrors in. The photo is before I added the mirrors, will try and post one later. But it looks class with the mirrors in.
PPS. lol total cost with glass and mirrors $250.00, to buy a cabinet like it would probably cost $1000,00 plus.
