The much anticipated HAF X arrives as the flagship of the popular HAF (High Air Flow) series. Designed for performance systems, this chassis is able to house today's latest and hottest CPUs, motherboards, graphics cards and is even compatible with USB 3.0 devices. With specialized support and cooling for graphic cards, massive airflow with the help of up to four gigantic fans and easy access to installed components, this is as close as it gets to a system builder's 'dream case'.

Excellent cooling is provided by four gigantic fans: one 230mm front blue LED on/off fan, one 140mm rear blue LED fan, one 200mm top and one 200mm side blue LED fan, as well as the air duct helping cool the latest graphic cards. Advanced cable management with rubber grommets keeps the interior tidy and neat and provides a better cooling. Thanks to the adjustable VGA card holder, you can install heavy graphic cards with better support. The transparent side window gives you a direct view of the inner system and the LED provides eye-catching fun.

Easy USB 2.0, USB 3.0, IEEE 1394a, e-SATA and audio connectivity is provided on the front I/O panel. This is an amazing case for the do-it-yourselfer who needs a lot of airflow and flexibility!

5 out of 5 eggsA Great Tower For Many Generations

Pros: Tower offers a full solution to every user!
-SLI/Crossfire friendly as the tower supports plenty of depth/space for any MOBO build in mind and incredible stock cooling from the various fans with additional room for further growth!
-HardDrive For Days - I currently run 2 HDD and 2 SSD with still much room to expand between the various drive bays.
-Clean Cable Management through solid valve connections for any preference of cable banding.
-Dust Filter - clamp - sweep - slide back in = awesome
-Set for Liquid Cooling Valves + CPU cooling brackets like H100i series
-Beautiful design and tough material "non cheap plastic bullcrap"

Cons: -Expensive
-Was hard to receive HAF X Blue edition vs Red
-Have to buy 2nd top fan
-Heavy "as expected because of the material"

Other Thoughts: I would recommend this to anyone who isn't looking for limitations to what gaming/performance solutions they can and can't achieve based on what their tower's space allows.

Hands down my favorite build yet and will invest many generations of new hardware with CM's very finest product yet.

5 out of 5 eggsNow i Can Sleep

Pros: This bad boy lights my room up at night with it's beautiful blue LED fans. My girlfriend had trouble sleeping because it was too dark. I thought about getting one of those night lights you plug into your wall but I'm a grown man and was to embarrassed to go buy a 10 dollar light. I heard cooler master makes great cases for computers. I don't have a computer. I used my schools for everything. When the item finally showed up in my home, i was full of excitement as i was opening it up. Goose bumps went up and down my arms and legs. But, sadly i found out you couldn't just plug the case to the wall. So i called twin brother and told him about the issue. He said, "You need a power supply, motherboard, cpu, ram, etc....". So, i was planning to use the computer again at my school to order the stuff i need but the school will not let me use the computers anymore because of virus i have down loading from trying to get free...... purchasing songs online. So ended up using my smart phone to order the rest of the stuff. A few days past and 1,800$ later, all the parts arrived. I built of first computer and now i can browse the web at home. My girlfriend is very happy at night. The LEDs light up the room majestically and it keeps me up at night. But, as long as she is happy. As a few weeks go by my girlfriend was getting more and more upset. Having built my first computer, i have grown quite fond of it. I find myself on it for hours and hours. I stayed up for 40 hours one time playing Don't Starve. That game is awesome. My girlfriend said that i was ignoring her all the time, or something like that, i wasn't paying attention. This computer is awesome. I recommend this for everybody that is looking for a computer case.

Cons: Turns out you need a power supply, motherboard, CPU, Memory, video card if you want to game well, hard drive.

5 out of 5 eggsBEST CASE SO FAR

Pros: Delivery was quick, this was my first time building from the inside so I initially felt overwhelmed but WOW this case gives PLENTY of room GREAT AIR FLOW and the instructions were clear.

Cons: The instructions were only pictures, some words would be cool but none the less clear on how to install/remove components.

Other Thoughts: This will last me at least 6 years so i 10/10 recommend it.

4 out of 5 eggsJust shy of excellence

Pros: The single most important feature I look for in a new chassis is that it has room to work, and this case delivers. There are a few tight spots, particularly around the drive cages, but this is by no means problematic for eve my fat fingers. Airflow is excellent, as you'd expect from a HAF series case, and there are plenty of options for fans and rads.

The tool-less 5.25 system gets top marks in two ways: it works better than any I've seen, and can easily be removed leaving a normally functioning bay. Functionality AND flexibility... awesome.

Cons: My single largest complaint is the CPU cutout, as others have already mentioned. Two cooler holes were completely inaccessible on the ASUS Z97 Pro board I purchased for this build, and all of the other boards I tested had the same issue. This is just a baffling oversight on CM's part.

Dust filtration is halfhearted at best. Maybe I'm more bothered by dust than most, but the provided mesh is pretty much useless for fines. Some kind of externally accessible, magnetic filters would be appreciated (and are available after-market for those willing to drop the necessary coin.)

Other Thoughts: CM's blocky, industrial look isn't for everyone, so if you're looking for a huge case with smoother lines you might try the Corsair 900D. Water coolers might also give this case careful consideration before purchasing, as fitting a 360mm rad on top is possible but challenging. I'd have preferred to see some offset holes for the top rad, too, as the current placement is somewhat limiting. Mounting options for 140mm rads/fans at the top would also be welcome. 200mm fans are fine, but I'd have liked flexibility.

All in all it's a good case, but not a great one. If you're already shelling out $200 for a case you're likely to be loading it with obscene hardware anyway, so unless you're sold on the HAF look I'd probably recommend the Corsair 900D for anyone looking for a monster case.

5 out of 5 eggsCM HAF X Blue Edition Review

Pros: Space. Loooots of space.
Front USB3.0, eSATA
SATA backplane for quick hard drive swapping
Room to put more fans/radiatiors, if needed.
Sturdy case chassis/panels
Front 230mm fan - lots if air movement with no noise
Casters in the box. Fully loaded, the case weighs a lot. WIth the casters, it makes disconnecting and pulling the case out for troubleshooting easy.
Thumb screws. Very easy to remove side panels and install PCI cards because they all use thumb screws.

Cons: Hard drive mounting strategy is kind of cheap. I had to try at least 5 different times to get the metal pin to stay in the rubber grommet when installing a 3.5" HDD. Maybe I'm just uncoordinated, but when I had a CM storm enforcer, the HDD rails were great and easy to use - these trays, not so much.
Heavy. Very heavy. To be expected, though. Large case.
Can only use VGA air duct OR side panel air duct, not both. Not a big deal because both provide adequate amounts of air flow to the interior.
Side 200mm fan connection gets in the way of closing the case sometimes. I probably should have routed the fan connector before everything else, but I don't feel like taking my case apart again.

Other Thoughts: Had to upgrade the case to fit the 970's. The HAF X is a monster of a case and you'll have enough room to fit any component in it.

5 out of 5 eggsAmazing case- Way too much space inside. I love it!

Pros: Absolute ton of space
Hot Swap Bays
Very pleasing design

Cons: 2 gripes and it's not a big deal.

User manual is written in 300 languages confusing to read.
Side install drive bay trays are made of plastic and you have to be VERY careful putting them back in and handling them. I would actually pay $20 for this design with metal trays instead of that plastic.

Other Thoughts: I was going to go with the Cosmos II but after seeing the actual size of this case in person I'm glad I didn't because it's more than big enough for everything I need. You could literally run Quad SLI in this thing and still have room left over for a full water cooling loop for everything.

It's insane.

5 out of 5 eggsCooler Master's Customer Service is Top-Notch!!

Pros: I've had this computer case for quite some time and have not left a comment that it deserves. For it's Gaming purposes, it's definitely one of the better, if not best, designs out there when it comes to cooling and design. The design itself may need a new rendition because of newer cases coming out, but for functionality--it's definitely worth the purchase. One of the USB ports chipped off because of possible continuous use and Cooler Master, despite not having a receipt, was willing to replace the I/O panel. I just received a brand new replacement without a hassle.

Cons: None.
