Insert pins terminals in case, using soldering iron is easiest solution, nuts as well.

Other electronics can be inserted as well at this step.

Cable from dc supply should go through hole on back cover, to terminal pins which are input to buck converter.

Yes I went bit too deep with soldering iron while inserting nuts, and yes it is bit crowded inside (some heat shrink tubes are recommended on critical joins). But it works, and its much prettier than before.
