Die cast display case ideas needed

I have a small collection of Ferrari die cast models including some of the BBurago 1:18 scale models, and a few of the Hotwheels 1:43 scale models along with some others. Nothing too fancy or expensive... but I am out of room on the shelf I was using to display them, and in the future I am looking to double, triple, or even quadruple my collection size. I'd like to upgrade to a nice display case, and I had the idea of using a couple different cases, and creating a sort of "scenery" display or something.

I was thinking maybe a garage "scene" with a car on a lift, some others with the hoods open etc. and some work benches and boxes.

Something like this below. Anyone have any ideas, pointers, or sites to visit for ideas and or to purchase stuff like this?
