Cooler Master has released a new line of high-end gaming cases, the Cosmos II. The C700P is one of these cases and is designed to house a custom water cooling loop. In this article we will compare both models and see which one comes out on top.

The cooler master cosmos c700p is a high-powered, fully modular power supply that offers superior performance and extreme reliability.

Good day, everyone!!! In 2017, we saw a massive transformation in the computer industry, beginning with graphics cards, moving on to processors, and finally to cases, which is fantastic for some individuals who have seen some significant changes in the PC sector. We will compare the Old Generation vs. New Generation, i.e. Cooler Master Cosmos II vs. Cosmos C700P by Cooler Master, in today’s debate.

Cooler Master’s Cosmos C700P is the most recent addition to the Cosmos Series, having been launched in September 2017. We have waited long enough since this case was announced for promotion at Computex 2017. It drew our attention not only because of its features and appearance, but also because we were curious to see whether this newest member of the Cosmos family resembled its family hierarchy in any way. So, without further ado, let’s get into the specifics of the new case and dissect the advantages and disadvantages of it and its predecessors.

The Cosmos series was published a long time ago. Cooler Master just launched their 25th-anniversary edition, which is a reimagined model of the old hierarchy Cosmos II, which is a complete failure since it is the same Cosmos II with colored curved temper glass. Cooler Master, on the other hand, has introduced the Cosmos C700P to its new Cosmos series.

Side View

It has a classic appearance and feel, but it also includes the 2017 trend of subtle LED components, tinted dual curved temper glass, and a fully configurable design with an inverted motherboard configuration option and improved IO Ports with the addition of a Type C connection. The new Cosmos C700P has adequate space for the most powerful XL-ATX motherboards and is made of a mix of plastic and aluminum.

Panel on the front

The CM C700P, like its predecessor, keeps the classic handlebars with minor changes in the top and bottom, which creates a strong first impression since they are perfectly integrated with the case’s curves. There are two panels on the sides, one of which is dual curved tinted temper glass and the other is a plain side panel, but both are curved to match the casing. The front panel features a power button, a reset button, a fan controller, and LED lighting customisation, which includes the ability to control the LEDs through the motherboard.

Aside from that, there are 4 USB 3 ports, a generation 2 USB type C port, and an Audio & MIC jack on the IO. Whereas the last version had 4 USB 2 ports and 2 USB 3 ports, the Power button was concealed along with other buttons, which was a neat feature to see.

Mechanism of the Panel on the Sides

The side panel is made up of a dual curved tempered glass panel and a matte finished aluminium panel that swivels sideways at a 90-degree rearward angle, which is the exact opposite of its predecessors. Unlike its predecessor, which slid down to expose the drives, the front has a bracket that when removed reveals the front detachable dust bracket. Removing the bracket reveals the twin 140mm fan bracket, which can accommodate a radiator up to 340mm with ease, something that the cosmos II and triple 140mm fans did not have.

On top of that, both generations can handle radiators up to 340mm in diameter, as well as dust filters. The only difference between the two is that the C700P has a nice LED effect on the top part, which makes it even better since it also lights the handlebars. The rear panels of both cases are almost identical, with a few minor changes such as the new chassis having eight PCI expansion slots rather than the ten seen in its predecessors. The PSU mounting bracket is also unique, with a raised platform that lacks the rubberized surface of previous generations. The bottom of both generations is identical, with the exception of a slight upgrade in the new casing.

Now it’s time to talk about the inside, with the goal of identifying a distinction between the two generations. The inside of the Cosmos II extreme is filled by an optical drive bay, two hot-swappable 2.5′′ drive bays, and five 3.5/2.5” HDD bays. There is also a fan bracket at the bottom that, when opened, exposes six 3.5/2.5” drive bays.

To summarize, the old Cosmos II has a total of 11+2 hot swappable i.e. 13nos of HDD storage capacity, whereas the new one has up to 2nos of 3.5”. You can increase the capacity by purchasing new ones as it is a case of modular approach, but it doesn’t make sense because the case is quite expensive and the separate accessories are also quite expensive.

Furthermore, there are three 2.5” drive bays in total, one in the front and two in the rear, one of which is already filled with LED and Fan controller. This has a significant effect on the C700P’s storage options. Another thing to note is that there is a metal plate that is linked to the PSU and may be used to conceal the drive bays. However, the metal on that plate and the PSU shroud is readily stained by figure print.

Furthermore, the PSU shroud is not connected to the rear part, making it a little wired since it wobbles easily. Both cases can accept full ATX or EATX boards, however the C700P has some additional features, such as the ability to flip the motherboard tray using the included guide, despite the guide’s inability to give a clear image of the process. The next generation casing also lacks the hot-swappable drive functionality.

Unlike its previous gen cases, which are relatively less beautiful, the new Cosmos C700P is a highly robust and very appealing looking case with all of the absolutely superior exterior mix of color. Though, for $300, this case provides a little less. More drive cages, as well as the LED and Fan hub being located separately, would be a nice choice, and the power shroud should be connected to the case itself to eliminate the wobbling problem when the side panel is removed.

In this premium category case, the supplied fans seem to be of poor quality. This case is geared at PC enthusiasts and the modding community. Due to the above circumstances, the case seems unfinished, but in terms of Appearance, it closely resembles the previous Cosmos. It’s true that it’s the most recent Cosmos product, but there should be more to it.


The cooler master cosmos c700p black edition is a high-performance, mid-tower gaming case that comes in a variety of colors. It features an innovative cooling system with dual 140mm fans and three preinstalled 120mm fans.
