Cooler Master Cosmos C700P review: Big and versatile

The perfect blend of old and new

Interior and cooling

The inside of the Cosmos C700P is remarkable as well. The first thing that stands out when we open the glass side panel is that while the motherboard tray is visible, the bottom of the case that houses the power supply and about seventeen centimeters at the front of the case are behind metal panels. These shrouds are secures by regular screws which makes them easily removable so that you have better access to components during their installation.

The Cosmos C700P can house Mini-ITX, Micro-ATX, ATX and E-ATX motherboards with a maximum dimension of 30 by 28 centimeters. The case also offers multiple ways to mount the motherboard, which is a pretty remarkable feature. Aside from the traditional method it is possible to rotate the motherboard a quarter, something that Cooler Master calls the chimney mode. After all, hot air rises and by rotating the motherboard in a way that allows the connectors to point upwards you can use this. When the motherboard is rotated, the connectors that are usually found on the back of the case end up inside of the case, after which you can route the cables outside through a hole in the back. Connecting peripherals happens inside of the case and not on the outside, which means that you have to open the left side panel in order to connect cables.

The Cooler Master Cosmos C700P offers three different ways to mount the motherboard.

However it is also possible to remove the entire motherboard tray from the frame of the C700P, and instead of mounting it on the right side, you can mount it on the left side in the frame. This creates a BTX-like set-up in which the motherboard is mounted at the bottom of the case, inverted when compared with its normal position. Should you choose this set-up, you can also invert the metal shrouds that cover the power supply and the front of the case. You can even choose to convert the glass side panel from the left- to the right side. 

We tested the case in the traditional layout, which is also how Cooler Master ships the C700P. If we remove the metal shroud at the front we find a sea of space behind it. Completely at the front of the case there is room for three 120 or 140 mm fans; two 140 mm models are already installed. If you want to you can also mount your water cooling here, which allows you to fit a radiator up to a maximum of 420 mm. At the top of the case there is also room for three 120/240 mm fans, or a radiator of a maximum of 360 mm. If you want to use the front- or top of the case for the biggest possible radiator, you do have to remove the cage for the optical drive. If you want to leave it in, the front allows for a maximum of a 360 mm radiator and the top a maximum of a 280 mm radiator. At the back of the case we find room for a single 120/140 mm fan or radiator and Cooler Master includes a 140 mm fan that is mounted in this position.

Sea of space

Next to the motherboard, at the front of the case, there is a sea of space that is available. Cooler Master placed a rail system here that allows you to mount cages for 3.5 mm hard drives, where you can choose the height on this rail yourself. With such a cage directly behind the position of the graphics card you can install a graphics card with a maximum length of 32 centimeters. If you mount the cages higher or lower - and you have plenty of room to do so - you can fit a graphics card with a maximum length of 49 centimeters in the C700P. Cooler Master includes two 3.5 inch cages, both suited for a single 3.5 or 2.5 inch hard disk or SSD, but in total there is room for a maximum of nine of these cages.

Looking at the back of the motherboard tray we find two 2.5 inch brackets for SSDs. However, one of these two brackets is used for the built-in RGB controller. If you want to mount more than one SSD you either have to give the RGB-controller another place in the case, or mount the SSD in one of the two 3.5 inch bays at the front of the motherboard tray.
