So I didnt even need a RJ45 socket, I checked a RJ45 plug against the cutout and there is simply no way it would fit in there. It doesnt even fit with the latch completely pressed flat against the top of the plug. They simply made the cutout just a bit to small for that…
I also figured out that even a fixed USB C next to 3 extension card slots is going to be somewhat hard to do, because there are these mounting posts in the plastic, one of which would be exactly where the USB C would need to be…
It might still be possible though and Ill definitely try to make include that…
