When they’re mounted on a PCB I don’t think that I would include them.
I don’t understand why people are losing their shit here. If the DN is modular on the inside there’s nothing wrong with putting the PCBs into another housing.
The big question is how the PCBs are connected (my guess is some ribbon cable) and whether there are any software dependencies to the keyboard or controller parts which would cause trouble once the boards are missing. If this wouldn’t work out or if I want to sell the device, I’d just assemble it again.
