Test System

Assembly

The Cooler Master Cosmos C700M sports the same type of functional modularity as in the C700P, so be sure to check out the disassembly here. This allows you to install your system's motherboard upside down or rotated by 90°, which would have your GPUs face upward, for example. While you can certainly install your motherboard with the whole tray set outside of your system, you may not need to. In our case, as only a GPU was used, I was able to skip that step and place the board directly without having to use any of the traditional expansion slots. Instead, as I used the GPU stand, the ribbon cable was used. This is a pretty cool spot for a GPU, but you want to make sure you do not block the HDD tray unless you are willing to move the tray above the graphics card, which may not end up looking very sexy.


To add a 2.5" drive, you first have to pick where you want to place the unit: behind the motherboard, underneath the 3.5" tray, or on the metal shroud to show it off. I chose the more understated location behind the motherboard tray. Here, simply take the bracket off the motherboard tray, slide the drive into place, and screw it down. It sits behind the metal cover instead of on top, which means you won't see the SSD once the bracket is back in place.


Adding a 3.5" drive to the tray is done with the use of special screws. Simply place the drive on the rubber cushions, secure it with the long screws and place the tray in any of the many possible positions on the hard-drive plate.


With all the innovation within the Cosmos C700M, the optical drive bay keeps things simple and traditional. Just take off the drive bay cover, slide the ODD in, secure it with two screws and you are done.


Due to the massive size, you are free to add any power supply of your choosing. It sits on the sturdy tray and is secured with four screws, just like in any other chassis out there. You can easily reach the bay by sliding the PSU in underneath the shroud or, if need be, can also take that cover off to give you an unobstructed angle of access.


With all the parts installed, the case looks gorgeous and clean when viewed from the main side. Even the backside of the motherboard tray is fine due to the metal cover. I did not end up using any zip ties just to make a point: you don't really need any. Fully assembled, the C700M looks pretty darn sexy, albeit a bit empty due to its sheer size.

Finished Looks

RGB Color Gallery

The Cooler Master Cosmos C700M does not only come with a built-in addressable RGB controller as you may also use any motherboard with the functionality to sync up all the lights from the board, fans, strips, memory, and case. There are seven distinct colors without the built-in controller, or you may set the chassis to breathe through all the various hues. However, the main attraction is RGB mode, which looks very sexy.


Cooler Master has done an excellent job in slimming down the lighting elements when designing the Cosmos C700M, so that none of it feels overwhelming, unlike in the C700P. On top of that, the power button now lights up in the same colors as the rest of the chassis.


Looking at the rear, the Cosmos C700M makes a pretty normal impression, and you could forget for a second that this is one massive chassis. However, looking at the curved, tinted glass panel, you are brought back to reality. The tint is nice and light, so you should have no issues showing off all your cool hardware.
