Look insideEach side panel of the Cosmos S can be removed without screws, pull up the handle at the rear of the case and the panel falls open, easy access to the internals in a matter of seconds.
The right panel is your standard black brushed aluminum affair, Coolermaster no longer uses the noise reduction foam on the panels inside the Cosmos S, understandable as one of the new side panels has a huge 200mm fan attached to it.
On their specification sheet at the site they clearly mention that if you have a larger tower CPU cooler, you will run into problems fitting the side panel with the fan, the manual also explains how to remove the side panel fan, it requires a bit of screw-work but it’s a one time affair.
The inside of the Cosmos S is quite different, the previous version had those 6 custom hard drive bays and bottom fan feeding fresh air to the VGA area. The “S” version has no fancy HDD bays, but a 4in3 device. There is no VGA air duct either.

We do get the same handy 5.25” bay device tool free installation “clips” which just need to be pressed in to secure the device. This work flawlessly with full length devices as DVDRW; extra screws are required for half-length units like Fan controllers.
The HDD bays sit in the bottom of the 5.25” bays, but can be moved to any place you like:
The hard drives are screwed tight in the bracket, then the bracket is mounted on rubber rings onto two plates which are then in turn screwed tight into the 5.25” bays.
The PCI brackets are held in place with thumbscrews, a tried and working solution for easy tool free installation, without issues for dual-slot VGA cards.
CoolingIn the photos above you have already spotted the 200mm side panel fan, and 120mm rear exhaust. There are two additional 120mm fans in the Cosmos S, one is located in the 4-in-3 HDD bay:
The other is located at the top, where there is now room for up to three 120mm fans:
Optionally you can add a 120mm fan at the bottom of the case, there is already a dust filter present to keep out any unwanted particles:
The top panel is held in place by one thumbscrew, once removed it gives you access to the 3x120mm mounting holes, you can install fans in/outside the case, there is enough clearance for 120x120x25mm models.
Even with a DVDrom installed you still have room at the top to fit a fan or radiator.
A closer look at the available space:
The Cosmos original design incorporated water-cooling friendly options, the Cosmos S goes one step further and gives you the possibility to mount a triplex120mm radiator without the need of dremel; further prove this case is build for extreme enthusiasts.
A demo shoot with 3x120mm fans at the top panel:
If you water cool all your internal components, VGA, CPU, chipsets, you need some airflow around the CPU socket and general motherboard and VGA area to keep things cooled down, that’s where the 200mm side panel fan comes in, providing a tremendous amount of airflow to all components inside the case.

As much as I am liking this case for how well it fits my needs, the price is a bit to high to swallow. Might at well look at the MountainMod designs, as they start at the same price.
