The following may be "overkill" for many a SOHO pf implementation, but this motherboard comes with FOUR (4) embedded intel (em) NICs. It retails for approx. CAD$235. You may use either of, E3-1200 series XEON, or I3-2100 series CPU. (For price reference, a quad-port intel NIC is typically CAD$400+ by itself.)
The i3-2100 CPU is at a nice price point and provides more than enough punch for SOHO/SMB deployments.

Why four is good -- one outside (red) interface, one inside (safe), one for WIFI AP, and one DMZ.
