Maybe not the prettiest, but a little cleaner than it was when it began. If I had it to do over, I might use a small 9.5" rack if such a thing existed. Originally I had the Netgear and patch cables in a Square-D circuit breaker box but it seemed unnecessary and a bit cramped with no air flow. I then added the Firewalla and moved the fiber over with all the other gear. I have room to expand but I don't think there is anything else I will ever need to add to this location. I have another networking rack more centrally located in the house. There was also tons of coax here but I coiled it up and tucked it away in case it is ever needed again. I originally wired my house with 2 network drops and 2 coax drops to each wall outlet. This spot services 6 drops to my office, two lines to my main networking rack, and the main internet connection.
This is great advice and had I thought/known this I might have chosen another backer material. I just used what I had laying around. Elsewhere I installed cement backer board for this very reason. I just didn’t think about this equipment or the wiring being of concern. I will look into the Intumescent coatings.
I would say it is seriously low risk in a residential configuration like this, and not worth stressing to much about tbh. I happen to have a couple years of experience in IT and have had to bring data centers into compliance for this sort of stuff before, and figured I'd share what I know.
