Install Upper Cabinets

What happens here

Cut and assemble the remaining plywood pieces into cabinet carcasses for the upper sections of the built-in, similar to step 2. Apply wood glue and use screws for assembly. Carefully lift these upper cabinets into position above the previously installed lower units and desk section. Secure them firmly to the wall studs and to the adjacent cabinet units using screws, ensuring everything is level and plumb. Add any necessary internal dividers or shelves.

Goal: Assemble and install the remaining upper cabinet carcasses, securing them above the lower sections of the built-in.
