My current home OpenBSD gateway runs on one of the small Atom-based (Z3700-series maybe?) NUC-alikes (I forget who made it) I picked up 2 years ago. I think I spent less than US$200 on Amazon for it. Very low power and I doubt the CPU has ever hit 5% utilization. If you go this way, make sure you can load an alternative OS on it; apparently some of these things refuse to load anything but Windows 10.
