I'm not sure why, but my RPI4 become broken 4 times in a row. I returned it 3 times, but finally I gave up. Every time it eventually stopped to boot up and there was solid green and red LED light. There was original raspberry PI case, modified to mount Noctua 5V fan, with additional holes to allow air circulation. There was original power supply. It was only connected with ethernet, this fan through GPIO and HDD drive through USB. Now I have HP T620, can be bought cheaply, it's definitely bigger than RPI4, but finally it just works.
