I have installed the NASPIcase and it works beautifully, running Ubuntu server without issue. My installation was performed on an SD card, but I want to boot from SSD.
To migrate the OS from the SD card, I used ddrescue to copy the OS from /dev/mmcblk0 to /dev/sda. Raspberry OS does this with a menu option --- but I don't want the training wheels approach, and I want to run a more vanilla OS...
The migration went perfectly, and even booted :D and the fan control/power button works beautifully.
The issue that I have is that the small blue LED below the power light is now flashing when I boot from /dev/sda It a "fast" flash...looks to the casual observer it would be continuously but upon inspection it looks like about 4-6 fast flahes then an extremely short "off" period
The htop looks normal, the filesystem is cleanly mounted (reported on boot) -- I don't see this documented elsewhere.
The powe rlight is on, the red PI power light is on and the LED activity light on the PI is flashing as I would expect a hard drive to. This only odd behavior I see is the blue light below the power swtich flashing
