I'd be quite surprised if this were very noticeable. Considering the usual shiny black computer case, versus an optimal black body radiator.
as in shiny vs flat black.
be it degrees Celsius or degrees Fahrenheit, using Kelvin temperature is a better measurement for variation between colors/colours due to wider spread of numbers between end points.
one link, even tho a '.gov' page, i do disagree with in that his wording would make his opinion correct;

some wikipedia links that deal with visual, radiated, and absorbed;

At any rate, it's unusual to use the case as the heatsink, unless you're buying one of those expensive silent PCs. It's the fans that do the heat dissipation.
if you do not want to cremate the cpu, be sure you have a fan or two.
I can't help but think that this thread, long ago, descended into theoretical absurdity. ;-)
true, but what else to do. ;)
