Recommendations for custom case to fit BBB + cape

I’m wondering if anyone has experience/recommendations for getting a custom case made for a BBG + cape. I need cut outs for the USB + ethernet at one end and some 4mm sockets from the cape at the other.
Not sure whether to try custom case or off the shelf case and adjust cape to mount in an off the shelf case. If its an off the shelf case then it would just be a case of getting cut outs done.

I had posted this yesterday on beagleboneback mailing list by mistake, I only noticed this when it wasn’t on my daily digest.

Thanks, Iain
