If the kegerator in question does not use the cabinet skin as a radiator for an underlying condenser loop - thus either has an external grid-style tubing condenser in the back, or uses an under-cabinet radiator-style condenser (typically fan-driven) - you can coat the thing with concrete with no operational concerns
But if it relies on the cabinet skin to get rid of heat, things aren't quite so cut and dried, as raising the thermal resistance to room air by a significant factor will put strain on the system causing it to run longer.
So, perhaps an 1/8" veneer would not be that significant, but I suspect 3/4" planking would be bad...

you're the man on stuff like this.
i got gifted a mini fridge kegerator, the built in temp controller was shot. but looked at the circuit and it just gave the compressor power. so i pulled the leads off and shorted them, and plugged it into a external temp controller. should i be worried about anything?
as far as i can tell the built in one was pretty much the same thing, and it's working with the external one....
any other HVAC people got any ideas? how low is too low for a mini fridge, i was cold crashing my 10 gallons of beer, and the compressor did get hot? but i had the fridge set to 30f. with a 15 gallon fermenter stuck inside with 70f beerf for hours...is that risky?
basicly the compressor is plugged straight into the wall with only my temp controller to say other wise.
