The best enthusiast case EVER??? 24 Jan 2012
By Super Dragon - Published on Amazon.com
This case is hands down one of the best cases I've ever seen and its really close to perfect. Here's why:

The good stuff first:

1. Huge case. If you were looking for a case that holds almost everything you want, Congrats, you just found it. OK there are other cases out there that hold plenty of stuff like the Mountain mods cases but they dont come with all the fans or accessories by default you have to buy them separately.
Here is what this case has in it: room for:
a. 10x 120mm fans
b. 13 drive bays.
c room for a full liquid cooling kit.
d. room for extended power supply.
e. m-atx ATX E-ATX XL-ATX SSI CEB and SSI EEB motherboard form factors.
f. 11 expansion slots
g it can fit a 140mm fan in the rear
h. 1x 200mm on top.
i. 2x 120mm fans on the side (optional)
j. can fit 2x 140 mm on top. (optional)
k. 4 channel fan speed control.

2. The case is made of steel. (not all of it though)
3. the bars (or handles) are very sturdy
4. the front door merely needs a touch and it slides down automatically.
5. side panels come off easily.
6. the case is easy to clean because you can remove the dust covers easily.
7. looks stylish.

Now for the negatives:

1. the case has a lot of plastic in it. I would prefer more of the case to be aluminum or steel like the top fan grill as well as the retention clips that hold you're 5.25" devices in place.
2. No side window as of this writing but the side panel has noise dampening material in it.
3. This case weighs in at no less than 47.3 lbs. Imagine how heavy it will be with all your hardware. For me this isn't much of an issue because I don't move my PC much.
4. $350 is a bit much to ask for a case that's not 100% high end. By that I mean that it is not completely built of steel and other materials
stronger than plastic. (like aluminum) Still you're unlikely to find a case for this price that has so much to offer.

Note: If you're in need of more information (or you need to see more of what the case looks like) you can go to YouTube. and type in Linus tech tips cooler master cosmos 2. He has a video that thoroughly looks at the case.

OMG, Unbelievable wire management. 22 Feb 2012
By Damian - Published on Amazon.com
Verified Purchase
First off ... this case is huge and heavy ... and huge. Tons of room for a boatload of hard drives. Wires dont run inside the main compartment of the case which clutters the innards. Instead they run out through the back of the motherboard area through slots on the side of the case which massively minimise clutter inside. First of all just looking at it is beautiful, it is a well thought of and designed case. From the nice sliding mechanism for the front panel to move up and down for showing of the CD/DVD drive in front to the sliding panel on top which covers and protect the power and fan control panels in-front of the system from wandering hands.

Both door panels easily swing open from rear to front, and have the ability to just lift off hinges to help work easier.

The design of the chasis allows for maximum air flow to kelp keep your system running cool. Inside the case is divided into two main parts, the upper part with the motherboard etc, has its on air circulation. Aswell as the lower half of the case where the power supply is and optional hard drive are have their own air circulation.

The power supply at the bottom with its own sectioned off compartment allows for the thick cables to be managed easily down there and only snake up the what you need for where.

Wires are all managed behind the motherboard, which is on the outside of the frame, towards inside the right door (if you have the front of the case facing you.) Inside my case looks neat, clean and sexy, but open the side door where the back of the motherboard is and its a disaster ... looks like an AT&T switchboard. But it is well hidden with the design of the case.

At any given moment, my system runs at a nice 30-40 Celsius.

My specs are below ...

2 X Corsair Vengeance 12 GB ( 3 x 4 GB ) = 24GB
2 X Sapphire Radeon HD 7970
1 X OCZ Technology 240 GB Agility 3 SSD- 3G SATA 6.0 Gb-s 2.5-Inch Solid State Drive
1 X Western Digital Caviar Green 1 TB SATA III
1 X Intel Core i7-980 Processor 3.3 Ghz LGA-1366 (BX80613I7980) Intel Core i7-980 Processor 3.3 Ghz LGA-1366
1 X Corsair Hydro Series H100 Extreme Performance Liquid CPU Cooler (CWCH100) Corsair Hydro Series H100 Extreme Performance Liquid CPU Coole
1 X EVGA Intel X58 and ICH10R Chipset EATX DDR3 800 LGA 1366 Motherboards 141-GT-E770-A1 EVGA Intel X58 and ICH10R Chipset EATX DDR3 800 LGA 1366 Motherboards 141-GT-E770-A1

Nice case but questionable quality and overpriced 6 Jun 2012
By DGS - Published on Amazon.com
Verified Purchase
Space and Compatibility:

The case is very spacious and is compatible with many different motherboard sizes. The back panel on which the motherboard is mounted is very solid and well designed as well. It has the cutouts, stnadoffs, etc, everything at the right location. The only thing I would change on this is add more grommets closer to the SATA ports on most ATX motherboards. The way the back panel is designed right now, it makes it impossible to use angular SATA connectors on the lower row of the ports. I know the angular connectors are meant to be used at the drive end, but I would like to be able to use them at the motherboard end as well just so that I can route the Sata cables out to the back immediately after the port rather than an inch or so later.

Drive Bays:

11 3.5 HDDs + 2 Hot Swaps SATA Bays + 3 large 5.25" bays for CD Drives. So basically ample room for drives. But the drive bay sliders are plastic, flimsy and the rubber bushings with pins that hold the drive in place tend to rub against the casing making it difficult to slide the bay in and out of the drive slot. Would have liked metal bays and a better drive holding pin design for a smoother slide in/out action. Connecting the sata cables to the drives requires a tiny bit of force and I am not sure if the latches are strong enough to hold the bays in place when such pressure is applied to connect the cables. I managed but was not exactly confident. Last thing I want is a drive bay pushed out with the drive in it and fall out from the other end.

Air Flow:

The case has a decent airflow but I expected much better for the price. The front has a large enough fan but the since the drive bays are oriented side to side, I would have liked more open spaces in the top HDD cage. The way it's designed, I doubt if the HDDs in the top HDD would get much airflow, and I am very sure that once the top HDD cage has HDDs installed in all the slots, the front fan won't be effective at all on blowing air into the case freely as the HDD cage would block all the airflow.I think theres room for a design improvement for better airflow onto the HDDs as well as into the case from the front even for a sideways HDD cage orientation.

Cable Management:

Lots of tiedown options. Good channeling for user installed wiring. The only thing I would like them to add is better/discrete channel for the wiring for all the factory installed stuff - front panel controller, SATA hotswap bays and above all the standard case fans. They could easily prewire the case for "at-location" fan points. This will make it much more cleaner. Regardless, no complaints here.

Access:

10/10 on this one. The case design allows easy access for every single part that might be installed in the case. I like the HDD cage orientatation for easy HDD mounting/removal and connection.

Now the bad:

1. The MOLEX connectors for the fan controller and the hot swap drive bays are the worst quality I have ever seen. Extremely flimsy. The pins are all bent and easily slide back when I try to plug in the frmale Molex power connector from the power supply into these. I am worried that there might be a lose contact which could cause data corruption (if power is lost even momentarily at the wrong time during a hot swap bay disk I/O) or worse still a constant jittery/noisy power connection may even ruin the hard drives in the hot swap bay.

2. The HDD fans are extremely noisy, especially at medium and high speeds. I think these are cheap design/quality fans which explains the noise. Cooler master insists (Yes, I did chat with them) that it is because of the high speeds but I I find it difficult to grasp that they couldn't design/source better quality fans that are less noisy even at high speeds. Note that I am NOT talking about the wind noise. I am talking about the motor "whrrr" noise.

3. The front large fan is noisy at higher speeds too although not as noisy as the HDD fans.

4. One of the side panels had a significant enough dent in it. The box was super clean and had absolutely no damage. Packaging was good. So this has to be from the factory. Someone probably thought that they should send it out instead of wasting the piece and deal with it if an RMA comes in. Either that or QA is completely lacking.

A note about Cooler Master warranty service experience:

I chatted with them about the issues I experienced above. Here's what they said:

1. The molex connectors are fine and it's normal for the pins to wiggle a little. They tried to play it down a bit and eventually said that those are the only molex connectors they use and even the replacement would be the same. I am honestly shocked to see such poor quality molex connectors for the price they ask for this case

2. The HDD & front fans are noisy because of the "tunneling" effect and the high speeds. If I don't want the noise, then I should use the fans only on low speeds. Again, I perfectly understand the wind noise at higher speeds. But a drone/whhrrr is not wind noise and is actually motor noise. The motor is just extremely noisy at medium and high speeds and I have doubts about it's longevity. The noise might even get worse as the fans age!

To Cooler Master's credit though, they offered to send me replacements for the Side panel, HDD fans, front fan, front panel under warranty. So plus points for that. But, they want me to pay the shipping of the defective parts back to them which means the net cost of the case to me will be even higher. They also won't do an advance exchange which means I can't use the case until for a couple of weeks (The front control panel also has a molex connector that is flimsy and the case won't operate without it). It also means they want me to go in and take the case apart to get the front controller panel out to be sent in.

All in all, I expect much better for the price I paid. I think I will just request a replacement from Amazon, although I am worried that the replacement might also have the same issues. I really don't want to add to the return rate but I don't want to spend money out of pocket on warranty RMA shipping either (although I am okay with spending some time to work on the swap outs if it helps keep the returns and eventually costs for everyone involved to a minimum).

At the moment I am undecided on whether:
* I should return the case altogether and go with Xigmatek Elysium for much lower price (I can get it for 160 brand new) albeit with some compromises
* Return and seek replacement from Amazon (this is what I will most probably do)
* Pay out of pocket and go through the hassles to seek Warranty service.

Bottomline: A well thought out, highly functional and aesthetic design. But riddled with bad compromises by Cooler Master on quality of many of the parts. Way overpriced for what it actually is, but there aren't very many options out there with features *as well as* the aesthetics. I wish they had spent less resources on the almost hydraulically smooth sliding front door design that adds absolutely nothing to the usability of the case and used those resources towards some of the parts where it actually matters.

3 stars for now as I am absolutely shocked at the quality of some of the components for the sky high price. I will update the review once I get a resolution on the issues I am having. If anyone has any specific questions on the case, please feel free to ask via comments and I will try and address those in my review.

Case is great~Customer Service? meh. 9 Jan 2013
By Karma007 - Published on Amazon.com
Verified Purchase
Me: I love this case. It's beautiful. It's elegant. It's imposing in size. It will hold everything I plan to put in it. I loved the case when I saw it used for the Dream Machine 2011. It has been well received by reviewers and builders alike. Does it do everything for everyone? No. So who should buy this case?

This is a 5 star case if:

1. You already think the case is beautiful as is. As in, you aren't immediately thinking man this case would be perfect with a window (cause at this point it doesn't seem like it is going to get a factory built option for 1). The construction of the doors apparently makes the process for a window very difficult. I have seen some beautiful mods of this case, everything from painting to windows, to one that looks like the eagle gargoyles in NY. So it's possible. But it isn't easy and I dont think they made it with modding in mind. It's a super car, not a hot rod...people don't normally mod their super cars. I hope that analogy makes sense. If you're looking for a hot rod base to build your dream case, this is probably a three star case.

2. You plan on using air or a mixture of air and liquid cooling or a moderately heavy amount of liquid cooling. I say this because a lot of the complaints seem to center on the inability to put the largest radiators in any configuration natively. They designed the case to have a lot of room and a lot of air flow so you will be able to push your CPU and GPU's fairly hard without the need to liquid cool everything. If you're a bench marker who wants to be able to put a 4 80 in push pull in the top and 3 60 in the bottom push pull and..and...it may take a little creativity and moderate modding. But it's not necessary for people who are simply trying to get more out of their computer for work or gaming purposes and don't need to break any over clocking records. Should you knock the case for not holding every rad you want to put in there natively? I don't think so. But if your deal is benchmarking and you have a lot of large radiators, this is probably a 3 star case again for you.

3. You want a machine that looks like a beastly machine, owned by an adult out of the box. The fans have LEDS and it will take all the lights you want to throw at it. But it looks beastly out of the box and says, I am a bad ass computer without having to do anything.

4. You have a lot of room under your desk. Or a large sturdy desk to put it on. It starts out at 50 lbs empty...so. And yeah, those people complaining about the amount of plastic...it's 50 lbs with materials used now and you would like them to add more steel...interesting.

so to sum it up. if you love this case when you look at it, when you read about it, you will love it when you build in it. 5 star all the way. If you are a modder or want to liquid cool every chip on your mother board for benchmarking then it will be a challenge to get all your radiators in there. Some of you love that sort of challenge so go for it.

UPDATE: 1/14/2012-I have dropped my review of this case to 3 stars because of a lack of responsiveness on the part of cooler master support. The fan controller I received was faulty. I put in a part replacement request on the 4th. The web site states that replacements ship in 3-5 days but 10 days later my request still says pending as though no one has even taken the time to review my part request. I will consider revising my review upwards depending on how this is resolved but as of now im not impressed with the level of service I've received after purchasing their flagship model.

UPDATE 1/17/2012-I just got off live chat with the customer service superviser. When I say got off live chat I mean that the customer service supervisor ended the live chat. I contacted them regarding the lack of a status update with my parts request submitted on 1/4/2013. I originally bought this case because not only did I like this case but it seemed like they had top notch customer support. Boy was I wrong. 2 weeks later no part shipped out. When we originally spoke on 1/4/2013 this same individual said nothing about a delay, let alone a delay of 2 weeks. In discussing what they would do to make things right (in the past they have sent out small gifts, like a mouse or fans when customers had bad CS experience, he said they would do nothing. that they had posted a note on the website regarding orders placed over the holidays not shipping till the 3d. I said, I made my part request on the 4th. He said, it says they would start shipping on the 3d. I say, so I should have assumed from your note that there would be a 2 week delay on my part request even though when we spoke you mentioned nothing of the sort? He said he would get the part shipped out and ended the live chat...while I was typing. When I tried to reconnect I get a message in my browser "This service is not available. We apologize for any inconvenience this may cause. Wants to argue for 1 hour even though a solution has been provided."
Now, no matter what's going on, there is a level of respect a customer should be able to expect from a company he has spent money with. Add to this that our conversation lasted about 8 minutes (not an hour)! Add to this that this is their flagship case. Add to this that this is to replace a DEFECTIVE part out of the box! And you can see how frustrating this is. I will never spend another dime on another cooler master product, and if customer service is important to you I suggest you stay far away from this company!

Great/Good case, serious limitation 22 Sep 2012
By Matthew J. Demille - Published on Amazon.com
Verified Purchase
There's plenty of info about this case, so I will skip a full review. The case is great, save for one serious limitation. The clearance between where the motherboard will sit and the top of the case is VERY low. My Corsair H100 (a THIN rad cooler) won't fit push configurations, let alone push/pull. You can pull out of the top of the case, but depending on your' motherboard, you won't be able to put fans, or at least one fan, on the bottom of the radiator (motherboard heatsink and cpu power socket are in the way). For a case this expensive, this is unacceptable. Just some thought for you who are considering the case for it's liquid cooling capabilities.
