@dwarf I have fedora 37 server installed on it. So far it runs pretty darn smoothly for something not using more than 10W.

For hardware I picked some g.skill ripjaws (see https://wiki.odroid.com/odroid-h3/hardware/ram, I have the 2x8gb version of the one listed there) and a crucial p5 nvme. For extra storage I have a crucial mx500 sata ssd. I have not yet had any problems with it.
