You should be able to route 10gbps with a whitebox PC containing a recent intel Core CPU (say, 5th gen or later) and a decent NIC such as Intel X540 or similar.

Sure, but that NIC is $274, so not cheap for casual home users.

Mellanox adapters are generally pretty cheap on Ebay:

* there are plenty more

Anything from the ConnectX (series 1) model onwards works decently in Linux (CentOS) & FreeBSD.

Casual home users don't need 10 Gbps to the home.
