The Cooler Master Cosmos S is an attractive and sleek case that looks even better than the standard Cosmos, holding its own in the higher end of the market when it comes to look. If the Antec P182 is just a little too plain for your tastes then the Cosmos S is an acceptable compromise between that and a Cooler Master Stacker 830 Custom.

Looking at the Cosmos as a whole, it’s clear to see that the re-design has mainly focused on improving the look and accessibility of the chassis rather than making the fan cooling capabilities more powerful. That’s a mixed blessing obviously, but to us the benefits of this door-less and funkier design (that looks great in champagne grey) outweighs the unimproved fan cooling. It's also worth bearing in mind that the Cosmos S seems more aimed at watercoolers too – there’s room for a self contained radiator and so forth in the top.

Simply put, the Cosmos S isn’t the best case we’ve ever seen and there are other chassis’ out there that can outpunch it in most areas – but we like the overall aesthetic and, if you’re a watercooler, it could be seen as great value for money (especially compared to the Silverstone TJ-07). However, when you consider that the Cosmos S is 25 percent more than the original Cosmos and doesn’t improve cooling performance, you have to ask whether that extra cost is worth it. We love the thought that has gone into the case’s design and some will definitely see value in the improvements made—especially on the watercooling front—but it’s not for every man and his dog.
