The closest thing I can find to that would be an Asrock J3455M motherboard. It’s pretty close to what you’re after, being micro ATX, has a couple of slots for network cards, DDR3, SATA3, and is fanless. And the price is reasonable.

Hello, what motherboard would you recommend that offers the same specs as the: (ASRock QC5000M, A4-5000, DDR3-1600, SATA3, HDMI, D-Sub, mATX) ?? – I’m looking for a fanless / low power consumption router to build.

When it comes to fanless options, small form factor, lowest power consumption etc… there aren’t much options.

Thanks for your input.

Yes, the power consumption with this method will limit the appeal to people who really want the higher-grade security, or to people who want experience on an enterprise-grade firewall and/or router. It’s not the same as administering Cisco or Juniper equipment, but the key concepts translate, and I do find pfSense devices in corporate environments so being able to administer pfSense will be directly useful in some jobs. Having experience with it isn’t a bad thing to mention on your resume or Linkedin profile. HR won’t know what to do with that but a good hiring manager will know or be curious enough to ask.

If you really want low TDP, the easiest option is a low TDP board like something based on an Intel J1900 board and a used Intel-based dual NIC. BSD support for the onboard NIC will be spotty. The cost in the end is likely to be higher but like you say, the power consumption will be lower.
