Looks pretty awesome. Seems like it's going to be years before home internet connections (at least in the USA) will be commonly above 2.5 Gbit.
My plan is one of these, I'm waiting on servethehome to post their review, they had a two similar models reviewed, but without the Intel N6005. Apparently they ordered the N6005 unit and are waiting for it. I believe it was mentioned that it's using the desirable rev3 version of the Intel Ethernet chip.
My plan is VyOS, Linux+Shorewall, or maybe OpenSense on the topton. Planning on Comcast modem -> Topton -> switch with 10G (for NAS) and 2.5G for the rest (desktops, 2xUbiquiti wifi, and a few Reolink cameras). Not sure if I'll virtualize the firewall (as discussed in the ServerTheHome article), but I will likely run DNS (unbound), maybe a cache, possible a Wire Guard end point, and maybe even a minecraft server for kid and her friends.
I'll use VLANs on the firewall so I tag each port of the 10G+2.5G switch as needed to let me separate the trusted (like the desktops I admin) from random consumer equipment I don't trust. I definitely want to keep the switch and router configs in version control. Sure it's overkill on the router, but I suspect I'll find a use for it over it's useful life.
