Pi4b metal cases and heatsinking. https://discord.com/channels/546776636352364576/644764264502001674/1011444841118453842 . I'm experimenting and will post results. I went with the Flirc cases because of cost and for ADSBX feeding, you don't need access to the headers for the camera, GPIO's etc.. YMMV, but I see no compelling case for adding GPS or any other external sh*t to build a reliable ADSB-X feeder, so that's why I went with a case that encloses the whole Pi4b board.
