I'm designing a new desk for myself, with modular units for the "pedestal". Each side of the desk will have one or more of these of various widths. Each is a separate box (sides, back, bottom) made from 1/2in plywood with hardwood fronts (face frame, drawer front, whatever, not shown in photo). I'm wondering... what would be the best joinery to use to assemble the plywood box part - rabbet+glue? biscuits? lock miter? pocket screws? something else? a combination of the above?
