So, here it is in all its glory - Cooler Master's Cosmos S chassis. We talk frequently in our reviews about how aesthetics are very much in the eye of the beholder, put to this reviewer's taste the Cosmos S is one fantastic looking case. While the general shape of this chassis is very much similar to the original Cosmos, the front of the bezel is markedly different. For starters, the cold-rolled sheet steel used by the Cosmos of old has been replaced by the use of aluminium in the Cosmos S, which in turn makes this case over 3 kilograms lighter, weighing in at 13.8 kg compared to 17kg for the original Cosmos.
