Having purchased the Arduino board for assessment (if stationary use is emerging it is more than likely I will use a so compact, micro or nano), this card was loose in a box with all components and tools used for advanced editing (various shields, diodes, perforated plates, screwdriver, multimeter, etc.). I found it useful to protect the Arduino board. This case perfectly fulfills this role. Only when plugged a shield that becomes inappropriate. But it's not a real problem because it is easily disassembled and back. Its transparency allows to see the LEDs soldered on the map.
