Which OS do you use for your homeserver?

TrueNAS scale with truecharts for my main server. I'm considering rolling out a compute only server with openSUSE microOS to leave trueNAS only for storage. I like openSUSE philosophy and microOS with cockpit seems solid on my tests. I might start with some old laptops and deploy the ldap server there to test it and remove that responsability from TrueNAS.
