Keys, i use this board for all my routers now.

Its the perfect thing for a router.
-
Dual intel Nics.
-Atom x64
-Itx form factor.
I run that with smoothwall.
It is tucked inside a Habey case, which is HORRIBLE for anyhting else besides an ATOM.

I needed either that or, go with a morex case with a picupsu.
I have it on a 2.5inch 200gig 7200rpm laptop drive i had during a SSD upgrade on a laptop.
I threw in a spare 2GB SODIMM module i had left over again in a upgrade.
Smoothwall Express 3.1 x64 installed on it without a hitch.
I have hammered it with torrents, and anything else you could possibly hammer it with and it doesnt go down.
I have also used the VPN without a hitch.
I have built about 3 of them.
one for my house, and two for my cousins all without problems.
I dont have wifi on my router tho, i have it connected to a switch, which then has Ubiquiti's Unifi AP's attached to them to get my wifi.

I required placing 3 AP's though out my house to get full coverage at 5 bars, hence why i went that route.
And yeah, i get signal even half a block away.
My neighbor even came over and asked what the heck i was running for him to always see full bars even at his house next door.
