Bit-Tech published a review of the Cooler Master Cosmos

All in all, the Cosmos is a solidly built and attractive case which performs well enough in heat testing and runs near silently. This alone puts it high in the upper echelons of PC cases, but it's price point is a little awkward and shaving just a little off the cost would instantly make it a much more attractive case. Pound signs aside though, the Cosmos is a worthy addition to the Cooler Master range and a good buy for anyone who can spare the dough.
