Cooler Master Cosmos S Review


Computer cases seem to be alive at the moment, what I mean by that is well…they are growing pretty big. This is partially due to the demands of the latest high end hardware, such as SLI and water-cooling. But also, gamers and overclockers are fan boys for large cases. So far, we haven’t really dealt with large cases at Tech-Reviews – – aside from the P190 – – so today; we’ve got another fat ass computer case. Introducing the Cooler Master Cosmos S…

The Cooler Master Cosmos S arrives in a black fairly hefty box – – bigger than most case size boxes. At the front of the box is the Cosmos S logo whilst at the back of the box are detailed photos of the case and its features.

Cooler Master Cosmos S Review

Stopping the Cosmos S from being damaged during shipping, there are two large polystyrene inserts protecting the top and bottom. There is a gap between the sides and the box, so they will not be damaged. Once the case is removed from the polystyrene, you will find the Cooler Master – – sealed in a brown fabric pull string bag. Emblazoned on one side of the brown bag is a silver Cooler Master logo. Its unusual packing a case in a fabric bag, as I’ve only ever seen it been done once, that was on an Antec Sonata 550 Plus. However, I do like the idea and it gives a good indication of quality before even revealing the case.

Alongside with the case, there is a whole bundle of accessories:

  • 5.25” to 3.5” brackets
  • A large bag of screws
  • EPS extension cable
  • Bios speaker
  • Lots of cable management ties and clips
  • Warranty information leaflet
  • Installation guide

This is all the accessories you’d need for the installation of a computer inside the Cosmos S. It’s also worth me mentioning that the installation guide is written in two languages, English and Chinese. Furthermore, there are many detailed diagrams showing how a computer is installed in the case and how various parts inside the Cooler Master work.
