I was in a similar situation and started with a Beelink Mini PC, which works well as long as it’s processor has Quick Sync available for transcoding video. The only problem here for me was redundant and upgradeable storage, so after a few months I build my own NAS in the Jonsbo N3 case. NASCompares on Youtube has great comparison and build videos for different cases and combinations.
