Barebones network appliance, 4+ GbE NICs, Intel chipset [closed]

Looking for a stepped-up ALIX or Soekris embedded network appliance to load pfSense and/or handle other FOSS-based network roles.

Main criteria is a GbE NICs (will be used for core routing/firewalling with managed GbE switches), DDR3 RAM capable, and multi-core/Intel Atom processor, in a 1U rack-mountable case or smaller.

Axiomtek has the ideal product but I don't think they have retail channels.

You can build your own around this Supermicro chassis. But you would need to use the 4 port Intel NIC to accomplish your goal.

Adding the following as a reference for anyone else who stumbles upon this question:
