The COSMOS C700P has way too many features that we want to highlight, so we’ll have to break it down to individual sections and highlight them one by one.

It’s worth noting that the entire COSMOS C700P can be stripped down to its bare frame by removing all of the screws – and they’re all using the same type of screw. Just keep in mind that it’ll be a mess.

This is the amount of screws we have to keep track while we were taking apart the COSMOS C700P.

The entire COSMOS C700P is built upon the idea of total modularity, and it’s really up to the user’s creativity on how they want the components to be mounted in the COSMOS C700P.

External features

Let’s just go through the external features first, and by that we mean that we’ll touch the outside first. We’ll strip it down as much as possible.

The side panels come off pretty easily. They’re held onto the case with pegs and hooks system at the back of the case, and swivels the entire panel to the front and secured with magnets. Popping the side panels on and off are quite tricky, as the side panels are large and heavy, yet the 3 pegs will have to be aligned and secured in parallel.


The removable fan bracket at the top can hold up to a triple 120mm or 140mm fans, or up to a 360mm radiator. I presume that you can do push-pull configuration here, given the excessive amount of space between the top of the case and the motherboard tray.

At the front, there are two removable layers – the face plate and a mesh cover. These two layers peel off from the top and then can be lifted up and out effortlessly, revealing the large opening for fan mounts.

It’s quite odd to have a single ODD mount here, obstructing both front and top fan & radiator mounts. And you can only have one ODD, as the front plate only has one slot.

You can mount a total of triple 120mm or 140mm fans again, or up to a 420mm radiator. That’ll require you to remove the ODD, though.

You’ll definitely need the bottom handlebar as it is the only piece that sits on the floor and has rubber pads.

The handlebars can be removed too, if you wish to do so. It’s held by screws and they can be easily removed. Just note that you’ll need a screwdriver with a long and thin neck. Else, the screws can’t be reached.

The back plate can be removed with a few screws too, though that requires you to either remove the side panel hinges, or remove the rear 140mm fan first. And yes, those side panel hinges can be removed too.

Internal features

Moving inside the case itself, let’s start off with the left side first. The COSMOS C700P has two covers – one PSU shroud and another hard drive bay shroud. As pictures do speak more than a thousand words in this case, let us take you through a series of pictures on how we strip the COSMOS C700P down.

We removed the left tempered glass side panel, then the right side panel, and then the two shrouds on the left side. This alone requires quite a lot of unscrewing work to be done. Then the shroud on the right side was removed. Eventually, we removed the hard disk bay too. That leaves the motherboard tray alone, which we also removed.


The motherboard tray is removed in an unorthodoxed way, which is through unscrewing everything and lifting it off the pegs and hooks, then taking it out of the COSMOS C700P itself. It’s a tedious job, and the user manual is definitely did not specify some of the hooks and pegs system.

Rotating motherboard tray

After wrestling the entire motherboard tray out of the COSMOS C700P for the first time, the mechanisms used on the COSMOS C700P will be much clearer. It will then be apparent that Cooler Master is using hooks and pegs system to have all the modular parts latch on each other first before screwing them in to secure the parts.

Cooler Master did advertise the COSMOS C700P as a case with rotatable motherboard tray, and we tried that out too. It’s fairly simple to do once you understand the mechanisms that Cooler Master uses.

The motherboard tray can be rotated in either 90° (chimney layout, motherboard rear I/O facing upwards) or 180° (inverted layout). We tried something funky, as we’ve only rotated the motherboard itself but the power supply remains at the bottom of the COSMOS C700P. Technically, it can be mounted at a 270° with the motherboard rear I/O facing downwards too, but we’ve yet to test that.

Mounting the motherboard in chimney layout will require another piece to replace the rear panel, so that cables can come out from above.

There is one thing I want to highlight – the front I/O connectors might have issues reaching the motherboard – especially the front panel audio jacks.
