Re: My office "showroom" build-out.
Here's an elevated Ikea Detolf. The base is 28" tall and made from an IKEA Akurum kitchen wall cabinet (15x30) cut down. It's paneled out the left and right with pieces cut from an Ikea Nexus tall kitchen door bought in the AS-IS section for $10. The door in the front is an Ikea Harlig, their lowest-end and lowest cost kitchen door line. It's push-to-open with the mechanisms I obtained essentially free in the AS-IS section ($1 for a bag of whatever you want). The Detolfs were originally bought used and their bases tops painted black from their original beech.
I have three of these in the office, the other two flank each side of my (currently very messy) desk. Every cabinet is wired for light, which will be provided exclusively from LED sources, operating at 12v. Mostly ribbon/strip cut to size, with some custom and some scale lamps and spot lights to provide dramatic shadows.
You can easily add a lock to your Detolf. *The best place to grab these locks is eBay - cheapest price, plus you can get multiple locks all keyed the same. *It would suck to have 10 different locks all using a different key.
Search for "glass cabinet door lock" - without the quotes.
Above the desk is an Ikea Besta wall cabinet with glass doors. I've removed the shelves and instead will insert acrylic display cases to hold rows of die cast cars.
In order to maximize on the usage of space in this room, I really had to get creative with the furnishings and make a lot of modifications to Ikea-sourced pieces. This is the central display case I made out of 3 Ikea Klingsbo units. I cut the legs off every unit and then bolted their frames together. I've omitted the back glass on each as well as the top and middle sheets of glass on two of them. They're sitting on an Ikea Malm 6 drawer dresser which I cut down on the right side to match the width of the Klingsbo.
The Klingsbos above are lit with LED ribbon light - 3 strips placed along the top horizontal frame of each cabinet section. This is the only cabinet that will be lit in a mostly even flood manner. Wired in series, with the wiring going back to transformers hidden behind a wall and operated by a standard wall-mounted light switch. In fact, the bottom switch to the left of the first Detolf image in this post.
I thought of using more Klingsbo units for another cabinet, but these things are expensive. Instead I decided to really maximize on space usage and use a customized base cabinet and two glass sliding doors that go from wall-to-wall in a nook I created by removing some closet doors from the room.
The glass sits on top of an Ikea Malm 3 drawer unit which I've also custom-painted. The unit is only just over 30" wide, so I've extended it to the right and made a cupboard there, using more Ikea Harlig door panels. I removed the top of the cabinet and installed my own top that spans the width of the entire nook (MDF, painted).
The glass was made to order, 6mm thick 30" x 64" and slides on rails from Knape and Vogt

Above and below, I'm the process of figuring out some additional shelving heights. The wooden shelf is only being used in this spot temporarily, it's actually the bottom-most shelf. All the other shelves will be glass, made with the left-over panels from the Klingsbo units.
I had originally intended this entire nook to be for Star Wars items exclusively. But in ordering the Hot Toy Tumbler I had to quickly make a change. The bottom-most shelf will now be Dark Knight and everything above it SW. This means I'm losing out on a lot of SW space, the collectible I have by far the most of. I'll be left with shelves of approximately these heights, from bottom to top: 17", 20", 9" and 18". The 9" has to fit a bunch of 3 3/4 figures and the top 18" the Hasbro 12" line Taun Taun and Dewback, plus as many other Hasbro 12" as I can fit. Not sure if I'm going to put the vintage (70's) 12" somewhere else yet... Above the Dark Knight stuff and below the other SW is the 20" tall Hoth shelf, mixing vintage, POTF and newer 3 3/4 items within a diorama.
