Model overview based on user reviews
The Cooler Master Cosmos C700M is a high-quality, full tower gaming case known for its large interior space and excellent modding possibilities. It features a beautiful design with RGB lighting and offers good ventilation. However, some users have noted that the fans included are not top-end, which is surprising given the case's premium status and price. While many appreciate its design and functionality, there are significant concerns about the quality of materials, with reports of the paint peeling and defective electronics causing lighting issues. Despite Cooler Master providing repair kits, these problems persist, leading to frustration. Overall, while the case is ideal for mega assemblies, its high price and recurring issues may deter some potential buyers.

A building for masochists - those who want to condemn themselves to regular problems and reassemblies. And also pay huge (for the case) money for it. Of the main undeniable advantages, the only thing we can highlight is the cool design. Everything else is debatable. Poor quality materials. The paint (black coating) simply peels off just from tightening the bolts. Most importantly, there are glaring issues with defective electronics. There are already 14 pages of complaints about this on the official CM forum. The lighting glitches! The strips freeze after a while, either stop working altogether, or display the wrong colors. CM is sending out repair kits to everyone - all panels with lighting and an updated version of the case controller, but this doesn't solve the problem. In my case, after replacing all the panels and the controller, the lighting worked for no more than 1 month and then glitched again. CM once again offered to send a new top panel. Thankfully, it's still free... But this is just absolute idiocy! A case of this level and for such money has no right to have such problems, especially systematic ones that repeat even after replacing the elements by the manufacturer. Also, my case was missing one screw for securing the case handle. And what if the handle broke off during transport, and this 30 kg giant fell on my foot?! Just insane... The price is astronomical, and the quality is just below the floor.  Evgeniy: use Cooler Master Cosmos C700M more than year |
