I suggested this in a recent similar thread: if this is a desktop, you could switch to an entry-level server motherboard with IPMI. Then run the IPMI cable to OpenVPN on (eg) an RPi or even directly on the router. You can configure and soak-test the router/RPi/etc locally, and IPMI is OOB. Using an RPi/similar has some nice properties: you could VNC to that and then go from there to the IPMI console, and also recovery images stored directly on the RPi would upload quickly etc.
