i tried CasaOS for a quick minute. its decent and just has the basics like setting up any disks and then has an app store. its really just a front end for docker and you can manually input the details of any docker containers that arent in the store

ive mostly been running docker stuff on my Synology nas. cant think of the model number now, 218+ i think, but any of the “plus” models will let you run docker. its very similar to Casa, no messing around with command line stuff. ive been self hosting for 10 years now and never touched the command line so i dont know what people are on about here saying you will have trouble

dietpi is another thing ive used on a few devices, mainly small SBCs and raspberry pi’s, but i think they might have a version that you can install on anything. its basically just debian, and it has a sort of a wizard) that helps set up various things like set up disks and install apps. its headless though so no GUI unless you install one, and the wizard is run from the terminal but youre not having to type any commands at least
