Kegco kegerator with hole in back

[Mrcmb]

I moved my kegerator today to sweep behind it and I saw this in the back? It was bought new feom kegco 6 months ago. Any thoughts on why this happened?

Is it just paint pealing or is that yellow stuff actually, insulation? Kind of hard to tell in your pic. Weird though, for sure.

Well I know my Kegco has a hole in the back by design so that you can mount the CO2 tank to the back, but that doesn’t look like a cleanly cut hole for that purpose. But to reiterate the user above, it is a little hard to tell what I’m looking at.
