Cooler Master Cosmos II Review

Rating: 9.5.

Today Cooler Master are launching their successor to the ever popular Cosmos computer case, an enthusiast favourite now for many years. The Cosmos II is an updated version, brought screaming and kicking into 2012 with a radical new design. The Cosmos II is classed as an ‘Ultra Tower' measuring a staggering 344 x 704 x 664 mm, able to handle the biggest graphics cards, CPU coolers and watercooling kits. We loved the Cooler Master Storm Trooper case when we reviewed it in November, so we have high hopes that Cooler Master will start 2012 on a very high note.

The Storm Trooper case is a huge design, but it is literally dwarfed by the Cosmos II. The Cosmos II has to be one of the biggest, heaviest cases ever made, weighing 22kg … the Storm Trooper by comparison weighs 13.7kg.

The Cosmos II is crafted around a heavy duty steel cage, with aluminum, mesh and plastic components around it. It supports the full gamut of motherboards, including Micro ATX/ ATX/ E-ATX/ XL-ATX/ SSI CEB and SSI EEB standards and is supplied out of the box with a total of five case fans for the ultimate cooling experience.

If you yearn for a system chassis with the ultimate storage capabilities, then rest assured we don't think there is another mainstream case on the market to compete. Yes, the Cosmos II can accommodate up to 13 x 3.5 inch drives.

  1. I think that looks awesome, the original was great too

  2. that is one hell of a case, but the weight would put me off. maybe they should have used wheels on it?

  3. I prefer the looks of the storm trooper case, but this is very attractive, I dont think it will be less than £200, even though they tend to be competitively priced cases.

    good job

  4. I almost bought the storm trooper but im glad I waited now for a while, even though I had no option due to spending all my money on christmas presents.

    This looks good and I plan on watercooling this year too, so ideal. the weight doesnt bother me, once its built, it will be sitting in my room.

  5. With a price tag of well over 250Euros (just like the original) i would also put that in the cons……

  6. I hope they’ll release a full tower companion to this..same design just a tad smaller and more affordable

  7. Hi Ted. Quite a few people have mentioned this so im sure they will take it onboard.

  8. Nice review seen it listed in the UK for £330 – guess I will need to get saving!!
