Pros: gigantic, gorgeous, lots of connectivity choices on the front panel, built-in fan controller, built for the largest MoBos, the Mercedes of cases

Cons: a bit too much cables


I've had a lot of cases. A lot of people have the habit of cycling through video cards, well, I have the habit of cycling through cases. I want the biggest and the best. And I can tell you, I have finally found my match.
I want nothing else, except maybe until a Cosmos III were to come out and it would look/be even better.

But let me tell you something: this is NOT a portable case. What I mean by that is: you just put it on top of your desk for the whole world to see, and you leave it there. It's too heavy to move it around too often.

Remember the weight of any normal, everyday situation full-tower cases? Well, double that weight and in some cases you might still not get close to the weight of this behemoth!

But for guys like me, that doesn't really matter. What does matter is its sheer size and its gorgeousness. I can assure you, people, if you have friends coming over to your place and they notice your Cosmos II case, they'll be drooling all over it. It's gigantic. You cannot miss it, it would be like trying to look past a mountain.

It's also gorgeous, and that's mostly, I think, because of the materials used. It's really high quality, all of it.

The front has a blue 140mm LED fan installed, and it looks beautiful. The sliding door works with magnets. It moves down sloooowly, so if you hate that, that might be a minor setback for you, but only a minor one. Behind the sliding door, there are 3 5.25" slots, and 2 3.5" slots with locks. You'll get 4 keys (one for each lock + one spare for each lock) to secure these locks.

The Cosmos II's front I/O panel has 2 USB3.0 ports, 4 USB2.0 ports, 1 eSata ports underneath two audio ports.

The top is one of the more beautiful parts of the case. It's got yet another gorgeouslooking sliding panel. This one does require a bit more strength to slide, though, and I advise you to keep your hand firmly on the sliding panel while it slides, because it has a habit of sliding back with quite a punch near the end. Once the sliding panel is out of the way, you'll notice phone-like metal keypads, meant for fan control, and a power and reset button.

Seriously, I don't get why people complain about this. I've even read amateur reviews on newegg from people who said they actually replaced the fan controller because they so disliked it. Seriously, I don't get why you'd do that. It works, and it works well. Plus, it looks nice. I don't even have to look at the buttons (read: even when I sit as straight as I can - and I'm nearly two meters long - I can't see the top of the case, it's really that big!) to know which button I'm touching.

Behind the sliding panel is grating. And beneath that grating is room for a 360mm radiator. I haven't actually tried it out yet because I'm still busy saving for a WC set, but I know for a fact you can't put in every single 360mm radiator. That is, if you want a push/pull configuration. Although obviously there are still a great many slim 360mm radiators on the market to fit your needs.

But THE most gorgeous featurre, I find, of the Cosmos II, are the doors. Forgot the serial numer of your RAM? No problemo! Just open the door, which opens like a car door. That's why I said in the pros that this is the mercedes of cases. Seriously, it's fantastic!

And the quality of the doors is amazing! At a certain point it's even nearly two centimeters thick! You could even place two fans in it, if you wanted!

The design of the doors is beautiful, although I do recommend to wash it with a little water once in a while, it does tend to get dusty at times.

The case is also supported by two stands, which bear the weight of the case well. Don't worry about vibration noise, seriously, the case is too heavy for that! tongue.gif

The inside of the case is gigantic, seriously. I could fit the biggest motherboards in it. The only thing they didn't provide were two CPU holes for those dual-cpu mobos, but how many of you have that one eh? smile.gif

The inside of the case provides for 10 expansion cards, which is the most I've ever had. Fit an XL-ATX MoBo in it and Quad SLI will be easy-peasy!

There is loooooads of HDD space, and the bottom HDD space is even cooled by two 120mm fans. The inside of the case is big enough to fit literally all, including the biggest, GPUs in it.

The only downside, I find, is that because of the fan controller, there are WAY too many cables. You have to be a bit of a thinker to get all those cables away nicely. But other than that, best case I've ever ever had!


nice, been looking at that case, wife says no so its a no but still i can appriciate from afar. Thanks, good review.. makes me want it more.
I love the looks of this case, it's super big and VERY good build quality. Excellent review man!
I have this case and am in the process of building the system (on hold now because I RMA'ed the MB). I like everything you and other reviewers have have said, but I'm puzzled about what to do with the wad of cables which are left over after you have connected the obvious ones. As usual with Cooler Master, the instructions are skimpy. (New Egg has a nice video of the product, and that helped some). I think it has to do with the monitoring capabilities which I don't really need. The Cooler Master Forum is (for me) impossible to get into. I've registered twice with different names and emails, but no access after 48 hours. So if any one has any advice about those cables I'd be happy to hear it. (I think I'm going to have to forget them.) Thanks for the review. Jack
