Looking for recommendations for a mini pc server to start self hosting - Lemmy.world

With all this migration i’ve been inspired to start self hosting some services. I am looking for a mini pc to ideally run linux and host a media server with radarr and sonarr, pihole and some other stuff as i start getting more into self hosting. Any recommendations / experiences that you can give? Or some general guidelines on what i should look for or things to avoid. Thank you!!
