Cougar Evolution Chassis Review @ OCC
 

Overall performance was about average. Idle temps were consistently a smidge higher than the other comparison cases and the chipset was noticeably warmer at idle as well. I'm not really sure what contributed to these higher temperatures, as the case body isn't much different than the others. Either way, it didn't perform significantly well or poor; it was on par with other cases in its category, which is a positive. At this point now, it's a matter of a degree or two and the comparison of appearance with competing cases.
