Yeah all fair. I actually got a Dec740 second-hand (I think it belonged to a small company that either folded or grew out of it) for a reasonable price, upped the SSD and the RAM, and now I'm building a router "platform" on top of Incus.

The idea is to run OpenWRT passing through the ISP NIC and one (or both) of the SFP+ ones going to the switch, and also run other services in isolated containers.

I'm even thinking about putting Home Assistant on a VM on it but I'm not sure yet what impact it will have on routing performance so that's on hold for now.

It's so much more powerful than what I need for the router/firewall that it should be comfortable to run quite a few things on it, and I can start moving them off it to other devices if Internet speeds catch up to it in the future.
