Well, the case I'm likely to buy is the mutant x one ( a cheap good looking one, with not too good ventilation).
But in any case the thing is I'm currently planning on putting 320GB, and later on multi-TB capacity on it, so I'd like to reduce the possibility of it all going out in some meltdown/fck off. That said, I live in a pretty hot place over here, and I do not want my pc to become some sort of heater/radiator. It's important for me that it does not radiate/emit excesive heat.
