Assemble Cabinet & Drawer Boxes

What happens here

Assemble the main floating base cabinet carcasses using wood glue and screws (e.g., pocket hole joinery or concealed screws). Ensure all joints are square and strong. Similarly, assemble the drawer boxes from the cut pieces, using wood glue and screws. The video shows a white cabinet structure being assembled, which implies these larger components are put together before finishing. If building separate floating shelves, assemble their structure as well.

Goal: Construct the main cabinet carcasses and drawer boxes.
