The Cosmos has an extremely spacious interior. There is an included VGA wind tunnel, which doesn't have too much affect. Cooler Master chose to save the user some time and include a motherboard chart, making standoff installation a breeze. In the back you can see the various accommodations for cable management and the IO panel cables. Cooler Master really lets you know that this is a high-end case by including the case accessories in a padded metal box. In the accessory box, you get keychain screwdrivers (one Phillips, one flathead), cable ties and all of the case screws you could ever imagine. Also, taped inside the 5.25” bays is another bag with an 8-pin PCIe extender and more cable ties. Obviously, the user seeking high performance will be spending a lot of time and effort managing their cables.
There is room for six hard-drives, each with its own slide-out bracket. Each bracket is equipped with four rubber grommets that make the only contact with the hard-drive, to help eliminate vibration. This means that each hard-drive requires four screws for installation, which can turn into a huge hassle. On the contrary, the 5.25” tool-less bay system is the best I have ever seen. Simply slide in the drive, push the button and enjoy.
There are two fans in the ceiling of the case, providing perfect room for a 2x120mm radiator for water-cooling, or just better air cooling abilities. In the bottom of the case, by the HDD bays, is the only intake fan. This fan's shroud can be pointed in any direction, helping the user pick and choose where they want the most cooling. At the power supply bay, there is yet more vibration dampening foam and you can see the exclusive intake for PSUs with bottom-fan cooling. Those with 80mm cooling on the end cannot take advantage of this intake, though. Moving just above the PSU are the seven expansion slots, which, like the hard-drive cages, are not tool-less and turned out to be very hard to access. Continue on as we throw some hardware in this case and wrap this review up.
