I was wondering if we ever might see a small 1U small business unit from gl-inet? If not, anyone can suggest one? No WIFI on it. Just good stable router with wireguard.
It does not have the 1U form factor, but a Brume 2 in Aluminum would work.
What’s your price point? A pfSense/opnsense box would seem to be your best option.
Of course when you get into 1u stuff you’re likely to not find appliances that are low power, fanless, etc., and they can be a bit pricey.
Hmm, I like GL stuff, The router does not have to be full 1U, it could have addon brackets to mount it in the rack. Price depends on features 
Get Flint v2 or Slate AX & a 3D printer. Switch the Wi-Fi off if you don’t want a Burme 2. It wouldn’t be the first time a 3D printer was used to solve a problem:
