If the concern is cost (rather than recabling the house) Mikrotik sells solid, inexpensive gear. Its management UIs take a bit of getting used to, but are fine once you've figured them out. You can also find two-port Intel 10gbit NICs on the Newegg "Marketplace" for ~40USD [0], and -while most already come with modules (and you will be informed if they don't)- if the X520s you're sold don't permit non-Intel transcievers, the NIC's firmware can usually be easily modified to change that.
