Used PC as OPNsense router?

[Irredio_Revancho]

Greetings People of OPNsense,
I have a 5-6 year old desktop that I planned to use with OPNsense. However it came with the infamous Intel Vpro and the Management Engine / AMT "features". A surprise bonus, not mentioned in the listing! It listed a 6 core i5-10500 cpu, 16gig ram, and 256gig NVME storage. New hardware with specs like those would be faster (not really needed), but probably 3-4 times more expensive.

Intel's CSME vulnerability detection tool reports the firmware patched, and the unit was made 3 years after the big scandal broke over the remote administration "feature." It has the most recent vendor firmware which got applied immediately after the shipping carton was opened.

How bad an idea would it be to use this system as a router?
A) A bad idea
B) A Truly Stupid idea bordering on lunacy
or
C) Maybe no worse a risk than using a cheap router made in a faraway land and sold in big electronics chain stores.

or, something else?

I just don't have the money right now for serious gear with the cost of ram, etc. I did drop $25 in the Donation jar last night.
Thanks for your thoughts.

Just disable whatever bothers you in the BIOS/UEFI and use it for OPNsense or Proxmox + OPNsense ?!

Also check if there are any BIOS/UEFI updates or alternatives like CoreBoot/LibreBoot/etc. for the used Mainboard :)
