I can only see the photo of the outside of the case, no documentation on how to use it.
It comes with a couple of antennas but I do not see any antenna connector on the board.
It comes with 3 standoffs and 4 bolts. If it were 4 and 4 that would be much easier to understand.
There does not seem to be any way to use buttons? They end up on the side that is inside the top part of the case, no openings there.
It comes with three stickers, two seem to be thermal pads but it’s not unclear why there are two, what is the intended placement. There is also one smaller sticker, purpose unclear.
