laffindude, can you post internal shots of this case? You said the PCB and plate are clamped between the two shells, but I'm having a hard time visualizing how this is actually implemented. KMAC has the plate clamped between the two shells too, but that's because it has tabs on the plate, and even then, the plate is still screwed down. Filco or CM does not have these tabs protruding out, so how is the PCB and plate held up without any standoffs?
If what you said is true and the case is more shallow than the stock Filco case, then a phantom PCB won't fit because it has a teensy controller requires a good amount of height clearance on the bottom PCB.
