This bezel was one of several custom items that we recently made for one of our customers - a larger post that covers the rest of the components will follow in a few days.
The bezel, and the panel that the bezel is housed in, are designed to sit in front of an LCD monitor, so we had to make some very low profile buttons that still operated but wouldn't be too deep. These buttons are able to be illuminated as well, although this isn't shown in the video.
Also, the button clicks are nowhere near as loud as they sound here!
Below are a few photos to show how it's been constructed ...
