For appliance-like quickly replaceable little servers like my firewall or other one off roles, they are ok for me, but to run my TrueNAS system (ZFS) I gotta run something with a Supermicro board and ECC. Mission critical workloads that need 24/7 uptime (homelab general purpose always-on server)!
I am running TrueNAS on it, honestly ECC is overblown out of proportion. This isn’t storing military state secrets.
