1. Have you considered moving the storage business to another host so

not to have a single point of failure? 2) Would a $60 Raspberry Pi 4GB be a good replacement? 2 USB3 ports and 1 GB ether port. My Synology storage appliance thingie is much dumber than that and has not missed a beat in years.

I'm using CentOS 7 and 8 for internal servers but use OpenWrt on a consumer router to do the fancy traffic balancing with the "cake" traffic control module, something the old kernel in CentOS 7 lacks.

Funny you mentioned the OpenWrt: I have been using one as access point and realized I not only forgot how to but cannot find info (I remember seeing it years ago) on how to run the 2.4 and 5GHz as separate networks. Well, I can't even get the internal dhcp to work, having to forward all that to my bind/dhcp vm guest. Shame on me, as if I get that working I can then think on putting a vpn between wireless and internal networks which is something I really should be doing.

I'm running an email server with Dovecot IMAP, Spamassassin, and ClamAV and that's a bit of a load so I suspect a Pi would be underpowered for that.

I really think it depends on the load, and only you have access to the performance info to answer that. There are people running all that in docker containers (I could swear I read about an "official" or "officially blessed" postfix container in the postfix mailing list).
