Internals

As I mentioned earlier, to remove the side panel you need to push on the tab at the rear of the case. The panel then folds outwards and can be removed.

Taking a look at the panel, you can see a 200mm Cooler Master fan secured to the mesh. Also, there appears to be one massive filter secured to the mesh – - to stop dust from getting into the case.

As we noticed from the rear of the case, the chassis of the Cosmos S is all aluminium, this is good as aluminium provides far better heat dissipation than steal – - is also much lighter.

Just like any computer case, there is a bundle of cables inside for power and the hard drive LED. The cables for USB, fire wire, eSATA, microphone and headphone are sleeved in black tubing. Weirdly, there is an ATX extension cable with two wires joined joining to it. After powering up the case, we realised these two wires provide power to LED’s which light up symbols for the USB etc sockets on the front.

Altogether the Cooler Master can support up to seven fans, although most ‘normal’ people would probably use three or four fans – - one front, one rear, one top and the side fan. Just four fans will give you immense cooling, but water-cooling enthusiasts will most likely want to make use out of all the possible fan mounts. As received, the Cosmo S arrived with four fans – – 3x 17dBA 120mm fans and the enormous 200mm side panel fan. All of which came with 3-pin: Molex converters.

To install 5.25” drives in this case, it’s very simple due to Cooler Master’s patented drive installation method. The method is very simple, just push the purple button on the drive bay and two pins will locate themselves into your drive, securing it in place.

The hard drives are secured in a cage – - which is completely vibration proof due to rubber noise isolators at the sides of the cage – - the cage takes up three 5.25” drive bays. Inside the cage, a 120mm fan is located at the front. Four hard drives can be installed in the cage, unfortunately though, to install a hard drive in the cage, you need to use screws to secure them in place – - no tool-less mechanism here, dammit.

A power supply can be installed at the bottom rear of the chassis. The power supply sits on a pedestal and has rubber-like material secured to the top, this stops any vibrations rattling their way through the case. To stop your power supply sucking up dust and launching it through the power supply, a dust filter is secured to the PSU pedestal which can be slid open easily and cleaned.

The motherboard tray has a card sheet taped to it; assisting you where to install the motherboard standoffs for different motherboard form factors. In the motherboard tray, there are many holes for cable management, fortunately, Cooler Master have given a bit of cable management guidance on the piece of card – - making cable routing very simple. Unfortunately though, this motherboard tray is not removable, however, if you haven’t noticed already, there’s plenty of space inside the chassis – - so installation shouldn’t be a problem.

Instead of using normal cross head screws to install various cards in the available PCI slots, the Cosmos S makes use of thumb screws for installation of your add-on cards. That’ll save you trying to squeeze your screwdriver in to install the screws on PCI plates.
