I've been looking for a SBC with at least 2 gigabit Ethernet ports to use as a router, firewall, and netflow generator on my home network.

I almost bought an Espressobin, but English-language websites only had the 1GB version and I just couldn't figure out Taobao to try and order the bigger one.

At this point I'm probably going to get a PC Engines APU 2 board, which is a quad-core AMD Geode processor w/ 4 GB of RAM. I can get it with a 60GB mSATA drive, a case, a wifi miniPCI board, and all the wiring for external wifi antennas for $243 shipped. That's a little steep but the other advantage is that the x86-64 architecture should make OS support easier, unlike all these little ARM boards that get one hacked-up kernel release and no updates after that.
