Cooler Master Cosmos II Ultra Tower reviewed - Inside and Assembly

Written by Sanjin Rados


Review: Unprecedented control with a saucy price tag


The case’s innards are physically split in two parts. The upper part will take a plethora of form factors, namely Micro-ATX, ATX, e-ATX, XL-ATX, SSI CEB and SSI EEB. The CPU backplate cutout is huge, which means that replacing CPU coolers will be a breeze as well. 




The PSU goes in a separate chamber, which is also shared by additional HDD cage. Cosmos II will take a total of thirteen 3.5’’, where six goes in the bottom chamber. Drivers are cooled by two 120mm fans (1200rpm, 17dBA). 




The air passes over the drives and goes out via the back side, through exhausts on right side panels. There are no metal walls that split the bottom chamber and the side panel, which makes routing cables from the PSU to the bottom HDD cage easy. 



Drive brackets are the same in all cages, i.e. they take 3.5’’ or 2.5’’ drives. 



The brackets are made of plastic but the metal mesh grill makes them look much cooler. However, we recently tested Trooper, the case that implemented brackets a bit better. Namely, the grommets on Trooper’s brackets cannot fall out, which is not the case with Cosmos II. 



Two fans sit in plastic door which can be removed easily – a simple lift on the front will release them from the brackets. The fans aren’t fixed very tightly in the door, so optional grommets will come in really handy. 



The bottom chamber holds two HDD cages, that can be removed by unscrewing four screws on the back. Two metal add-ons will let you mount a radiator with two fans in the place of bottom HDD cages. However, you can mount a radiator on the top and rear panels as well, so Cosmos II has you well covered there. 



Optical drives are held in place by toolless mechanisms. Below the three 5.25’’ bays are X-Docking hot-swap units. X-Docking is powered via 4-pin molex cable, i.e. you’ll need two connectors on each cable because each X-Docking requires own power. We instantly remembered Obsidian 800D case, which has four hot-swap bays, where all four are powered via a single SATA. 


There are enough cable management holes, which are also wide enough. Each hole has protective rubber rings held in place by metal clips. However, Cooler Master used some kind of flexible rubber that falls out occasionally when cables are pulled over it. We think that the rubber would’ve fit better if there were clips on both sides of the motherboard tray. For instance, Obsidian 800D uses much thicker rubber that doesn’t even need clips to stay in place. Cosmos II also has holes just below the top panel, which will come in handy with CPU power cables. 



Cosmos II easily housed EVGA X58 4-way SLI (XL-ATX) motherboard, HD 6970 graphics, and Thermalright’s HR-02 CPU cooler. Cosmos II allows for maximum graphics card length of 385mm and CPU coolers at 190mm. 


Cosmos II comes with 5 fans, which should be enough for most users. Naturally, the case offers much more than that and advanced users will know how to put it to good use. 



When the fans are at full rpm, Cosmos II ends up being quite loud but also very cool. The noise is considerably dampened once you close the side panels. The included fan controller offers three operation modes, where the fan controller’s lights will show which mode is currently running. 


Cosmos II can easily hold Quad SLI or CrossFireX setups. You can mount additional fans in the case (up to 10 fans), for instance, whereas the fan controller will take a total of nine fans.

Finally a case with some breathing room. I wish there were more full tower cases out there that didn't look like it was part of the autobot clan. I'll be ordering one of these for sure.

I'ld buy this case just for the door hinges. I've been looking for one like this for a long time. Modding normal doors isn't too hard, but for the price some of these cases go for... they should be built in.

Some people might cringe at the price tag but this is mostly an all aluminum chassis except for some bits and pieces. This case is mostly perfect especially if you want to stick an EVGA SR-2 motherboard in it. I have only one very minor complaint. I would have liked to have seen a windowed side panel as I like to show off my hardware.

Oh heck no. Windows look like crap after a while. I very much prefer the stealthy look. Wanna show off your hardware then pop off the side to show it especially considering how easy of a task that is with the Cosmos line.

Functionality > tackiness

A flat top would be nice then.

I'm always dumping stuff onto the top of my faithful Thermaltake Xaser V - in fact, my router lives there.

The top acts as a air tunnel for the top fans (like the other Cosmos cases). You would be loosing efficiency in cooling by making it flat.

How the hell would I be losing (not 'loosing') efficiency by making the top flat?! It'd still have holes in for air to escape.

It's only if whatever I dump on top covers those holes that I'd lose efficiency. (note: 'lose', not 'loose')

Although I mentioned my permanently stationed router, which does not cover the top vent on my Xaser V, mostly I was talking about being able to dump a thing on top of the PC case temporarily, versus not being able to put things there at all because they slide off the fashion-handles/roundtop.

Why desktops with handle on top is getting common? Does gamerz travel with desktop these days? Kinda odd, and i don't wanna carry my gaming rig anywhere unless necessary.

Well that price s u c k s. In US price is 350$ and in EU 350€ which is not the same.
350$ is around 274€, so here in the EU we are paying almost 80€ or 100$ more. :cry:
