This is a good value, large box but the description is either wrong or missing: All sides of the box are steel, painted blue. A white plastic frame separates the front and back of the lid, which screw directly into the plastic frame, not intended for frequent assembly/disassembly. The inner dimension is approx. 10 mm smaller than stated. If you plan to drill holes, note that there are L-shaped bars along the top left and right edges that connect the front and back under the chassis. Considering the design, this box is poorly shielded.
