Good box for a project. I would have liked it better if the front and back had metal-to-metal contact. If you want or need to ground the entire case then you will need to take this into account in your design as the end plates are attached to the plastic frames with self tapping screws. For the price, it's about as good as I've found for a gadget. (I'm a Ham Raido fan, so I always want my entire case to have the same electrical ground, it's HF stuff.)
