This is a case for the PanelDue4.3. You attach the mounts/braces to the board first and then add it all into the case. The mounts swing into place, so you place it into an aluminium 4020 or 2020 slot at an upward angle, then swing it down. it can be screwed in place if needed. there is a slot at the top for the memory card, and a USB at the side.

No supports needed.
