Build two identical frames from the 1x3 pieces using pocket holes and glue, sized to fit under the two hinged top panels.

Attach the two frames to the bottom plywood panel, set in 1/2" from the edge. A scrap of 1/2"-thick plywood makes a reliable spacer — run it along the edge as you position each frame instead of eyeballing the setback.

Cut the top panel into three pieces — one fixed center piece and two side pieces. Attach the center piece on top of the two 1x3 frames; this is also a good place to add extra 1x3 supports underneath to create a back or middle divider (a power strip with a 1x3 cable-pass divider turns this into a charging area). Hinge the two side panels on with the butt hinges, oriented so the hinge pin sits out the back when the panels are closed.
