That looks awesome but the price is scary (until you figure the value of what you're putting in it of course ....) . I have scrounged all the junk shops , second hand shops , auction houses , garage sales and anything else similar to get display cases from big shop counters to small standalone units . In the past I have also used aluminium sliding windows , you can get them cheaply from second hand building places already in a timber frame like in the listing below (only I used smaller ones and paid a damn site less) ,

It's pretty simple to put a plywood backing on it and shelves and you have a large glass display unit you can easily lock ( sliding window keyed locks are cheap at bunnings etc) . In a previous house (now rented out) I was building a mini room (plan to do this in my "ultimate shed" one day) with one wall covered in 100mm wide shelving 100mm apart and then a 3 panel sliding glass door on the front . It would have meant using a special stick with a padded hook to get models from the furthest end of the shelf since the door only opened in the middle but for a 3.5 meter wide lockable glass wall it would have been bearable
