Note: Case Assembly adds additional time for production. Timelines are here.

If case assembly is added, we will peel all the acrylic, install the adhesive strips and gaskets, and screw the case together. All that has to be done on your end is soldering (unless the PCB is hot swap) up the switch plate to the PCB and unscrewing the case bottom to drop it all into the case.
