I bought the Argon One Raspberry Pi 4 case. I use my Pi 4 to run Homeassistant. For this I use the Hassio image. After I had installed the Pi in the case, I discovered that due to using the hassio image, I was unable to load the software to control the on/off switch and fan control. As a result, the case is just a case. Even worse is that in this condition, following a power cut, the Pi does not power up when power is restored because the switch needs to be pressed to turn it on by default. I am disappointed that these conditions are not mentioned in the item description. If I knew this, I would have not bought the case. I have no problem with the speed if delivery which was next day.
