For my “info-beamer” display I am using the SunFounder Raspberry Pi4B Aluminum Case with Dual Fan as it is low profile. I have my RTC also plugged in, but it seems I can not configure it (yet, hopefully). I then use the EVICIV Raspeberry Pi 10.1" Touch Screen as the case. (replaced the case fan with a Noctua 40x10mm 5V PWM fan that is connected to the Pi for cpu control. This brings it up to three fans, the two on the cooler and this one on the case.
