Thanks demik. Those are good pictures. There are 5 posts on the case to screw down the PCB, and ribs on the case bottom to support the PCB to minimize PCB flex. Same as the Filco, the PCB is tilted at an angle, which is what is giving me trouble with the Filco case. When I find more time, I will be redesigning a new case for Filco, and if that works I could apply that to a Poker case later.
