“Very nice material and design at good price, but for PI 3, I think that a case with a fan is a better choice. With top cover removed, I get 56°C CPU temperature (without heatsinks). In another case with fan, I get 41°C (without heatsinks), and 38°C (with heatsinks).”
“This is a clever design that comes in five parts: the red base with non-slip feet and pegs on the inside to fit the holes on the Pi board, a red top with a large cutaway to allow for accessory cables, white sides and a white lid. They clip easily in place. Using just the base and one side is enough to hold the board secure should you want maximum access for GPIO and accessory cables. The base even has two clear inserts so you can see the LEDs.”
