Hi, Computer desktop cases now tend to have a black interior like this one: http://www.corsair.com/cases/carbide-series/carbide-series-400r-mid-tower-case.html I don't know what is the reason for this black interior finish to be so dominant in most of computer cases. One of the member of a tech forum advanced an explanation that black absorbs better the interior heat which then spreads the heat better outside through convection. However, when the case is closed. The interior is dark black anyway regardless of the color of the surface of the metal inside. Would the infrared rays still "see" the difference of color of the interior surface? BTW, if you happen to know why modern computer case is black, I would appreciate to know the explanation. Thanks in advance.
