The Cooler Master Cosmos C700P has so much going for it. On one hand, it is the brand's modern take on the legendary Cosmos line. On the other hand, the chassis represents the first new high-end case from Cooler Master in a very long time. This means the C700P has some enormous shoes to fill, and it mostly manages to do so.

With the C700P, Cooler Master is bringing the essence of the MasterConcept to the consumer market; the aim of having an essentially fully customizable chassis with the ability to buy bits and pieces to accommodate an ever-changing hardware setup or the evolving needs of the user. The case is also meant to be accessible to modders, which has it go along the lines of the "Make It Yours" mantra that is at the core of the Cooler Master brand these days.

The biggest strength of the Cosmos C700P is its modularity. The ability to take the case apart completely and be left with nothing but a frame is not only unique but also extremely well executed for the most part. The only issue here is the complex upgrade path should you want to change GPUs, for example, as the modularity comes at the price of having to take the system apart, just to reach them properly. Maybe using thumb screws here instead of traditional ones would have helped alleviate the issue a bit. Alternatively, Cooler Master could include a little tool to reach these screws without disassembly.

In regards to the exterior, the Cosmos C700P is a clear evolutionary step forward from the original Cosmos in many ways, but not in every possible area. The original Cosmos series aimed to push the envelope on material and construction - something the C700P does as well with the dual curved glass panel and elaborate handlebars. It also offers ultra-modern I/O with USB 3.1 Gen2 Type C - something the Cosmos II 25th Anniversary Edition was missing. Cooler Master also goes with the times by having built RGB lighting right into the case - with a very functional controller to boot. There is so much lighting that it may in fact be a bit overwhelming for some. The only downside is the somewhat basic fan controller. Here, it would have been nice to have more choice beyond a simple high/low setting.

Overall, the Cosmos C700P pushes the boundaries hard, both in terms of the interior design of cases and the material mix and manufacturing processes out there, making it a worthy successor of the Cosmos II.
