5 out of 5 eggsSilent Purring

Pros: Lots of Space
Very High quality build - zero issues with flimsy feeling pieces or screw holes not lining up.
Incredible cooling potential - mine runs ice cold with 2 of the 5 optional added fans installed (200mm, (1) 80mm)
Great Looks
Horizontal MB layout (why did they ever go vertical to begin with??)
Amazingly quiet - even with the 200mm fan and 2 additional rear fans
Fairly priced - none of this 150-300+ nonsense.
cable management and tie down heaven!
Awesome looks. and different. Love the atypical form factor
Along those lines: No LED Fans. If I want color, I will buy color - I prefer the professional, clean look of not having a circus show going on while working (or gaming or whatever).

Cons: To easily install fans and HDDs, and have good cable management, you really do have to disassemble the entire thing, including the HDD bracket in back, that was pretty annoying.
Space between the psu cables and hot swap bay's back end is a little tight - and that was with a modular PSU...

Other Thoughts: I didn't want to put it as a con, but really think out the space you plan to put this thing: Size. Yes, I read the dimensions, but it really is bigger than I expected, not a huge deal, just be prepared for a massive cube to arrive.
This was not the easiest build I have ever done by any means, but I love this case - the overall functionality exceeds my personal Full size Tower in terms of cooling capacity, and it looks better too IMHO.

4 out of 5 eggsAll but the hot swap bay....

Pros: Great design. Awesome and handy tool-less case. Easy to remove motherboard tray. Good air flow. Just enough bays for full sized HDD and a handful of SSD bays.

Cons: The motherboard tray is just a little too high, so putting an aftermarket heat sink on will likely prevent you from being able to mount a 120-200+mm fan on the inside of the top. Annoying but nothing bad.

The Hot Swap bays are nice but the SATA port chip has blown out on mine after a year. Once I pulled the whole backplane off and manually cabled my HDD's they were fine. But do yourself a favor and just pull this out right away. Would have saved me a lot of frustration in the end. This is what cost it one egg in the review.

Other Thoughts: Great case. It really is. Easy to clean. Easy to maneuver. Very well put together and sturdy.

5 out of 5 eggsRebate Update

Pros: Great case

Cons: How can it be out of stock, I was going to buy another one....

Other Thoughts: I originally gave a big thumb down for the rebate turnaround time. I had my dates wrong and, in fact, the rebate came in the time specified. Sorry, Cooler Master for the bad review, you’re still my favorite manufacturer.

5 out of 5 eggsExcellent case!

Pros: Fits full ATX boards
Plenty of expandability
3.5" internal HDD bays
Hot swap bays

Cons: Cable routing requires forethought and more cable ties than are included.
Could use another 5.25" bay, although I'm not sure where CM would put it.
Could use additional front USB (2.0) ports.
Dust filters should be included.
200mm fans don't fit with high-profile CPU coolers.

Other Thoughts: This case looks phenomenal, fits under the hutch on my desk, and has more than enough room for everything I need to fit in it. Initial setup wasn't difficult, with the exception that you can't use angled SATA cables in the hot swap bays. The revisions in the Evo version of this case are well thought out over the original, except, again, angled SATA on the hot swap bays would be nice.

Installing my system in this case wasn't complicated, except for the cable routing. No matter how much thought you apply to how the cables are routed, or how much you wrap up your modular power supply cables, you will invariably end up with kind of a mess downstairs. Access to the bottom part of the case is very restricted after the motherboard tray is installed.

I wish this case had 1 more 5.25" bay, so that users could have both a 2-slot fan controller and an optical drive, or a 1-slot fan controller, an optical drive, and another accessory like the NZXT Hue. That said, there's really nowhere to put it short of removing a hot swap bay.

The inclusion of front USB3 is nice, but it'd be nice if there were a couple of USB 2.0 ports included as well.

My CM Hyper 212 Evo is too tall to fit in this case with the optional 200mm fan on top, suggesting that watercooling might be a good option in the future. This case supports up to 240mm radiators in the front, and 120mm radiators in the rear, although 240mm rads may not fit well with longer GPUs if you want a push/pull. Fits my 280x quite well, though, and keeps everything nice and cool.

5 out of 5 eggsIts a case with an odd shape

Pros: Built a X999 Crossfire setup in this case. I bought the 200mm fan to install on the top for GPU cooling as that is a MUST! Case is "OK" TBH with you all, i wouldn't do another build in this case nor buy another one. Way to cramped and I shouldnt have gone off youtube recommendations for this purchase.

Cons: Needs a little more space, just not a fan of this case and will replace this case soon with a phanteks case

5 out of 5 eggsReally Cool

Pros: Just bought this case because i thought it would be awesome to have seperate areas in the case. The motherboard sits in the middle with the power supply and the hard drives underneath and on top the various graphic cards and processors, wireless nic and so on.
Cooler master did a great job of giving the case a lot of room, my r9 280x fits and that is one long card. You can get a 200mm fan and 2 80mm fans for improved airflow or liquid cooling.

All the extra bits are easy to remove or install.

Cons: I was concerned buying the case because it has a component that connects the hard drives to the motherboard, for added convenience, which has fried some peoples hard drives. So when i got it it took me 2 minutes to unscrew the component out and i was good to go.

5 out of 5 eggsBest Case Ever

Pros: 2x Hot Swap bays for Hard Drives.
Can hold 4-5 3.5 inch OR SSD's.
Tool-less mounting of HDD's and Disk Drives
High Air Flow
Can mount 2x 120mm OR 140mm fans in front (case comes with 2x 120mm silent fans).
Removable Motherboard tray with large cutout for CPU backplate
Everything sits HORIZONTAL. No worry of strain on your slots or CPU heat-sink.

Cons: Does not include a 120mm fan for the rear, or any of the 2 80mm fans that can be mounted to cool the internal HDD cage. But for an $89 - $99 price point, who cares?

Have to remove front panel (which is plastic with tabs) to clean fan filter.

Other Thoughts: Seriously, this is the BEST case I have ever used, or seen. I will be purchasing at least 2 more.

This can be an open air test bench by removing the panels, it can be a high-airflow desktop, or as a makeshift combat weapon/stool. Carrying handles are built into the support frame - grade A construction. Thumb screws. Tie down cutouts literally everywhere - including to those two 80mm fans. Removable dust filters.

You would love this case.

5 out of 5 eggsResistance is Futile

Pros: This case provides plenty of room for working inside the case with its removable top, sides and front. The 5.5 inch drive bays are tooless which was great for installing my BD drive but not so great while installing my fan controller. I ended up having to screw two screws into the controller and then force it in until one side clicked into place and the other just stayed there. While it is a very stable mount, it would have been better with some sort of adapter or if the tooless latches would have been on both sides. The extension on the back of the case, installing a PSU was a breeze. There is enough room to mount a total of 8 fans on the case plus the fan for the PSU so cooling and airflow is not a problem with this case. I have no use for the hotswap bays at this time but I can see where they would come in handy and will possibly use them in the future for transferring files to back up drives. The case is pretty heavy for a case, but that's because this case is a tank. It is made of thick steel panels and a nice angled frame that reinforces the case. Reinforced handles on the side provide for sturdy lifting points for moving the case if needed.

Cons: The space under the motherboard becomes very tight while trying to mount the PSU and run power cables to various part of the PC. If you forget to run a cable to certain areas of the motherboard, there is a chance you will have to take the motherboard tray lose for proper cable placement.

Other Thoughts: Overall I give the case a 4.5 out of 5 due to the tight space under the motherboard. The motherboard try is easily removed to mount the motherboard and install the memory and heat-sink. Depending on which graphics card you are running it could mount the card, however the r9 280 was not able to be mounted until after the tray was replaced.

The case does take up more space than a normal atx case but this is information that is available by looking at the dimensions in the specifications.

I would recommend this case to a system builder to use as a safe bench tester, someone looking to keep their internals cool, or someone just looking for a case outside of the norm like I was. The tight space under the motherboard is worth all of the space given to the customer on the top side of the motherboard.
