Is this a good first homeserver?

I don‘t know if this is the right place to ask, but is this an OK build for a first start in selfhosting? Is there anything obvious I could improve? I‘d mainly run Nextcloud, Immich, some Docker containers and smaller web applications and cronjobs.

Follow up question: Do I need a separate CPU cooler, or is the boxed Wraith enough? And how loud is it? I can’t really find info on that.
