This version has solid top and bottom panels; the same 8 x 10 x 5 in size is also offered with vented panels. The front and rear panels are 0.064 in thick aluminum that is easy to machine; each enclosure comes with one satin black and one contempra grey panel, and because the design is symmetrical either end panel can serve as the front or the rear.
