@retroman Because the pi 4b box has no power key location, direct use will cause pwr key is stuck. In addition, the size of the DP output port is larger than Pi 4b, and the size of the metal radiator of PI4b is too far from the DP interface. 3D printing is the only option before the surrounding accessories of the cool pi come out.
