Thanks for the feedback! Had similar problems with a raspberry pi. It cannot deliver enough power to the hdd, so it kept rebooting the drive.
NAS, perhaps apps like vaultwarden, nextcloud, immich, maybe grafana for sensors… I am not 100% sure as this would be the first.
Oh yeah, that is true. Mini PC has a proper ssd nvme.
Thanks for the feedback! Will look at the NAS you recommend, but i thik i want more freedom to tinker. Will definitely look into proxmox!
