Synology DS1815+ with 16 GB RAM, and a DX513 extension cabinet. While early versions were marred by the Intel Atom bug (I had mine replaced under warranty), it has been a solid performer. I backup to an DS1511+ (also with an extension cabinet) hosted at a friend, and host his extra box in return. The management software is very nice, and as it can run Docker, it is straightforward to augment with additional functionality.
