I’ve been running OPNsense as a VM in Proxmox for a year on an AliExpress box that doesn’t have ECC. If I might ask, why do you have a requirement for ECC?
Before this box, I ran a Dell R230 with pfSense but got tired of the noise and 40 watt power draw.
I’ve had zero issues without ECC, so I’m just curious about your need for it.
It will always be Twitter to me. X is a variable in a math problem… not a company name. Oh, I’m also lazy and have never used Twitter.
