Maybe I missed it, but was (plate) mounting type listed anywhere?
I don't see it anywhere either,
but there are no mounting tabs on the PCB, so not PCB mount;
no holes in the PCB for plate mount; and
no foam under the PCB that can be seen in renders, so I'm assuming either gasket/sandwich or topmount.
This board is all about looks for me though. No matter what kind of mounting, or even if it sounds horrific, I'll figure out a way to make it sound and feel good.
