I live in the SF Bay Area, and ended up with Sonic Internet, and a 10gbe connection. Routing this with anything off the shelf was going to be "very expensive".

I ended up with an Opnsense box. It's an m920q (i5-8500), with riser card and a dual SFP+ nic in it. All in, it was less than 200 bucks (now it would be closer to three). I ended up with a cheap, Chinese "media converter" (from aliexpress because the same thing on amazon is 3x the price) that just had two SFP+ ports on it. That let me go from an SPF+ copper ethernet module to a DAC and not dump a bunch of heat into the 1L pc.

I have to say that the functionality made it a worth while investment: traffic shaping, wireguard and the like have been mostly a joy. And the documentation for Opnsense made the setup and use (mostly) easy.
