Hammond ships these extrusion boxes with small selftapping screws, which are not that strong, ok for stationary use, and they will leave some metal fragments behind. The paint on those boxes also make threading a chore.
Better to use a #6 spiral flute tap, and then use longer SS screws.
Front and rear panels can be ~1.5 mm aluminum PCB, Use any standard solder mask color, even black, and leave text and symbols unmasked, and/or silk screened.
Alternatively use aluminum side out, and put SMT circuits on the inside of the front/back panel. Or even sandwich two together, precision is tops, and it looks great.
Takachi makes better extruded boxes, a little bigger,, with better end panels.
