This really is an excellent case. Very easy to set up and the full size HDMI ports are a blessing, no more hunting for adapters. Having all the ports at the back is easier and the on/off button works well. I thought at first that using the GPIO extender might entail some handiwork but it fitted with room to spare. Downloading and running the fan and switch software was no problem and the Pi has rarely gone over 49oC although I have yet to stress test it. Fitting a 250GB SATA SD again was no problem but the Pi didn’t seem to recognize it (probably due to me not knowing what to do)I could see it listed using lsblk but that was all. I took the drive out and fitted it to a PC to mount and format it, put it back in the Pi and it showed up no problem. I downloaded Raspberry Pi Imager to set the drive up with Raspberry Pi OS and that was it. The speed difference is very noticeable. I now have the Pi setup as I want it and made a backup onto a 16GB sd card using the Pi’s SD Card Copier (this does require patience). I cannot recommend this case enough.
