“wanted an 'open' case for my new rasp pi4 and felt that this case along with the fan shim would help keep my pi4 nice and cool. i like how the parts of the case sandwich the pi motherboard thus not adding to the dimensions of the pi4. the clear top and bottom show off the circuitry and the parts are well made and a very good fit. the brief utube video showing how to build the case is very clear and easy to follow. highly recommended.
