Amazing Case, Amazing product! Once the instructions were consumed, I set about pulling it apart to place into its cavernous space my Raspberry Pi 4. Following the instructions and using the provided screwdriver, putting this together was a breeze. I already had the Raspberry Pi setup, so I just plopped the SD card into the one on the back and it booted right up. I installed the software to control the screen and fan and it works a charm. I have installed a coin battery to power the RTC and now it boots up and shuts down to my schedule. All in all a fantastic device!
