I'd be quite surprised if this were very noticeable. Considering the
usual shiny black computer case, versus an optimal black body radiator.
As someone who lives in a hot country, where it can easily reach 50
degrees in my workroom, though it's more common to be in the 40s, in
summer (Celsius). I can't say that I've noticed any significant
temperature difference when I've handled the white- or black-cased
computers. It's much more likely for the case to absorb the ambient
heat, than help to cool the PC down. But I can certainly tell a big
difference if I touch one that's had the sun hitting it.
At any rate, it's unusual to use the case as the heatsink, unless you're
