A Closer Look - Outside

Out of the box, you will notice that the case is not only extremely heavy, but also bulky. The Cosmos C700M takes a lot of the design elements from the P variant, but looks considerably more refined upon closer inspection. Any curves except for those of the tempered glass panel, which is rather unique, are simple.


That piece of glass has been curved twice, which is quite the elaborate thing to achieve. Glass, unlike metal, needs to be heated to be curved properly, and tends to move as it cools down, which makes getting a perfect shape like this no small feat. Cooler Master placed a glass panel on the main side and a solid steel one on the other. You may buy an additional panel made out of glass for €69.99/US$69.99.


Taking a look at the front, it is, just like with the original Cosmos II, made out of a mix of plastic and metal mesh. Unlike the Cosmos II, which had a slide-down panel to reveal the drive bays, the C700M offers the same flip-forward cover we have seen with the C700P, which stays in place on the bottom, giving any external drives, like ODDs, enough space to open up fully. The plastic parts of the front still feel a bit on the cheaper side considering the rest of the chassis, but thanks to a more generous use of the material, it feels much sturdier than with the C700P. Behind that solid cover is a large metal mesh front. Upon closer inspection, you can see the pins which connect the panels embedded ARGB lights with the rest of the system.


Behind the metal mesh cover, you will find three retail-grade 140 mm fans set to push cool air into the case. They are mounted on a removable metal frame, so you may easily expand the cooling elements here to include a radiator of up to 420 mm in size, for example.


In the rear, the external design continues seamlessly—there are no breaks in terms of looks. It is quite the thoughtful touch as it ensures the design can be viewed from all angles. To achieve this, there is a removable plastic frame on the rear, which is held in place by magnets. While I see no issue with the strength of this mechanism under normal circumstances, odds are you will find yourself pulling the frame off unintentionally when trying to move the whole system, especially as its edges are quite sharp on the inside.


Taking a closer look at the bottom, there is a spacious PSU bay. Above that are the eight motherboard expansion slots, each protected by individually reusable covers. In the very top is another 140 mm fan, this time set to push hot air out through the back of the Cosmos C700M. This brings the total fan count within the case to three.


In the very top is a large brushed aluminium cover that may easily be pulled off to reveal a cooling bracket with enough room for up to three 140 mm fans or a 420 mm radiator. At the front of the top is an extensive I/O panel consisting of four USB 3.0 ports, a real USB C 3.1 port, and the usual audio plugs. Unlike the C700P, the entire top of the case uses aluminium, which looks and feels much nicer. On top of that is a large power and small reset button. Cooler Master has also built a multi-stage fan controller and an RGB LED controller into the I/O panel. With the Cosmos II, Cooler Master tried to push the envelope by providing a Motorola RAZR-style button interface, and it would have been nice if the C700M had something similar.
