Cooler Master has really surprised the market by releasing the new Black Label while we are in the middle of an economic downturn. The economy may explain why such a small number will be sold here in the US, a mere 10%. The limited numbers will surely make the Black Label a collector's item among those of us who collect rare parts. Still, others who do not consider themselves collectors will surely want to get in the action as well.

This is a very qualitative and Lightweight design, ideal for water-cooled with many places for refrigerators.
Also very good for use with air cooling, but only if it is not concerned about the noise the user.
To love immediately, makes the super towers like kandalf I have to look young in the true sense of lexeos.Prokeitai for the only box that I have not found yet elatoma.

Cosmos S looks mean and neat, especially when you install a whole system inside and turn everything on. The fun starts there, with red lights coming from everywhere - from HDD module to something we haven't really seen before - you actually have background light on the front panel of the case, as well. It just looks like a light show and just amazing in the dark.

Cooler Master has done it again with the Cosmos S case, they have brought a great looking case, with a simplistic design with excellent build quality, to the market that is also able to keep the temperatures down. Cooler Master took a look at the Cosmos 1000 case and improved on it and added the features to make the case better and released it as the Cosmos S case, which worked very well.

Technical Excellence

The Cooler Master Cosmos S has a number of improvement over the original version of this enclosure and I am glad to see Cooler Master has gone to 100% aluminum construction which make the case far more manageable and easier to move from place to place.

The Cooler Master COSMOS S excels in a number of key areas.  First off, there is simply so much room within this chassis that installing virtually any hardware combo will not be an issue.  The open accommodations also make it easy to work within the case, which is another plus.  The layout of the I/O ports is also very good, the cooling fans are quiet and perform well, and mounting drives is quick and easy too.  The only areas that could use some improvement are related to the push-button optical drive locking mechanisms, which could be tighter and the power button, which is overly sensitive.

As I said before, Cooler Master never leaves anything at "good enough", with each new case they are constantly refining and improving to make the best product available to the consumer. I am extremely impressed with the Cosmos S case and would not hesitate to recommend it to anyone in the market for a full sized chassis.

This case is one of the best cases I've reviewed. It's virtually tool-less, leaving only the motherboard and hard drives needing tools. I would have liked to see Cooler Master include additional thumbscrews for both purposes.

High End

 
madshrimps.be : March 2008
 
The Cosmos S, the Sport version of the original Cosmos delivers on its promise; it has a flashier exterior design, fancy new features and competes at the top end of component cooling performance. It is indeed true to the “Sport” tag Coolermaster gave it.

"The Cooler Master Cosmos S Case is mostly aluminum except for a few plastic parts. Despite this it’s still fairly heavy but this is due to its large size. It comes in a gunmetal gray color with black brushed aluminum side panels. This color combo looks very sharp and should match most home/office setups. This case has great styling and build quality, excellent air circulation, lots of room to work, plenty of drive bays, and much more. This is one of the top cases on the market. Watch the video to find out more and check out the bloopers at the end."

PC Perspective : March 2008
 
Cooler Master certainly out did themselves when they redesigned the Cosmos full-tower enclosure.  The new black and gunmetal gray color scheme with sleek curves and futuristic styling borrows queues from both race cars and starships.  The overall size and look is retained from the original Cosmos 1000 but numerous styling changes have been implemented on all sides and the Cosmos S is noticably lighter thanks to a new aluminum chassis.

The Cosmos S gave us plenty of room to build a system that can survive today’s hottest processors and video cards thanks to perforation everywhere and the 200mm fan did a really good job of delivering air where we need it. If water cooling is your forte then the Cosmos S gives you the room to make it happen, I can’t wait to see what the modders come up with for the 3x 120mm fan area along the top of the case, be it external or internal.

With the RC-1100 Cosmos S, Cooler Master has taken an already well-designed and award-winning chassis, the Cosmos 1000, and successfully pushed it to the next level. Some of the highlights include it being a very roomy chassis, effective cable management possibilities, aluminum construction, support for water cooling systems, and a touch-sensitive power switch. This "Sports" case is targeted at computer enthusiasts and gamers alike. We're pleased with the improvements made to the Cooler Master Cosmos S.......

The Cosmos S is nothing short of an amazing case. CoolerMaster have taken the original Cosmos design and made some major changes to make it look even more high-tech. The darker colors as well as the red lights used on the front fan, power button and connectors give the case a mean look that will feel right at home in any enthusiasts setup. The capacitive sensitive power button gives the case a unique feature while the connectors located on the top ensure file transfers to external devices will never be a problem.

The Cooler Master Cosmos S full tower case is definitely one of a kind. The first thing that caught my eye was that it looked like a hot sports car, thanks in part to the stylized meshed side panel that conceals a 200mm fan. Cooler Master really included many new features that I would expect to become a standard with high end computer cases, like the very cool touch sensor that replaced the standard power button. When building a high end computer system many user's focus on the internal components and not on the case, but with the Cosmos S arriving in March, the case should become a high priority.

The Cooler Master Cosmos S is without doubt one of the most well thought out cases I have ever encountered. From small things like the easily removable fan filters and quick-release doors, to the ability to install a monstrous triple 120mm radiator in the top of the case with no modifications needed, the Cooler Master Cosmos S has it all.

The Coolermaster Cosmo S is an exceptionally well made case, but it is not without fault. For one, the lack of a reset button, and strangely placed touch-sensitive power button will cause some frustrating issues. Providing the tight drive bays are sorted, this is an admirable case, with striking looks and powerful cooling.

Even though it does have a few features we'd like to see enhanced - for example the HDD drive arrangment and perhaps more attention to noise levels - and the price (at which Cooler Master says it will initially be sold for) is somewhat higher than we think the market will allow, the Cooler Master COSMOS S is, in our eyes, a well built, very attactive-looking case that extends upon the thermal control performance of the original Cosmos and offers a good solution to gamers and some power users.

The Cooler Master Cosmos S is an awesome case. There are many things I like about the Cosmos, but generally speaking, it's probably the overall adaptability to the user's individual needs. Like how the front drive bays go all the way from top to bottom and each one is available externally. If the user wants to put their hard drives at the top and the media drives at the bottom they can do that. There's plenty of room to install additional fans up front or even the top or bottom of the case if more cooling is needed. Top fans can be mounted inside or outside the case, allowing room to hook up a single, dual or triple sized radiator for water cooling. The included fans are all very quiet, even running at full speed.

“…I think the chassis is like a little slice of heaven.”

 

 

“Everything has been thought trough well, and that includes airflow, it's user-friendly, has pretty good cable-management, is reasonably in weight as the bigger parts are made in aluminum and on and on.”

“Everything about the case seemed well thought out and nicely implemented; the side panels slide smoothly into place with almost no effort and the touch power button is the type of thing we enthusiast end-users get goosebumps from.”

We say almost flawless because, the chassis still has some minor, minor things that can be easily overlooked, such the lack of some of the premium goodies included in the Cosmos 1000 or the jarring appearance of the cover for the front I/O ports, which is really a very subjective issue.
