Had an idea to use an ASRock 4X4 BOX-4800U for this, possibly as a VM.

If you look up the spec for this online, it comes with an AMD APU that's rated for 1080P gaming @ 15W, and has both 1gbit and 2.5gbit Realtek NICs. Anyone use this kind of setup yet? Also pondering running it as a KVM host, with OPNsense as a VM; I've done that before on other systems. Thanks.

I'd be careful with the realtek nics.  The drivers seem to do fine if you do not do any sort of netmap stuff (IPS/IDS). 

Enabling those types of services seems to make the nic crash.  At this time, I'd say it's YMMV.
