Interesting concept. It would be even more cool if you had a secondary USB input for power so you could do something like make the base out of acrylic instead and install LED strips to light the bottom. Since it's kind of modular, you could do wood, acrylic, aluminum, brass, or whatever else you wanted for the base.
The main problem I see is that you'd be relying on a PCB mount setup or a plate that might not be flush with the lip of the case. That could cause some issues. And if it is flush, the case may be too tall.
Definitely an interesting concept though.
