Building a router, where are the NICs?

[Coltin]

I'm not currently building a router, but I plan to in the future. I'm in the "looking up parts and dreaming about them" phase. I want to build a physical machine I can use as a router, but my google'ing skills are so weak I haven't been able to locate any NIC's (if that's even what I should be looking for) that have what I want.

I want something with 4 lan ports for my PCs, and be able to do wireless for the laptops. I know such a thing exists, but I can't find any for sale.

If it matters, I've been looking at pfsense as my OS.

Edit: I'm looking for places to buy nic's, online or otherwise. I live in Canada.

Quad port Gigabit Ethernet adaptors are easy to find (PCI-X or PCI Express). You'll have to buy a separate wireless adaptor. It will be an expensive solution, but you'll have a good performance router.

If your OS supports Realtek 8111C chips, you could buy a Gigabyte GA-EP45-DQ6 motherboard that already includes 4 LAN connectors.

What wireless adaptors can be used as a base station with pfsense?
