Cooler Master HAF 912 Mid Tower Chassis

Cooler Master’s HAF 912 further enriches the HAF series by adding a compact, yet fully featured mid-tower solution for enthusiasts and budget conscious gamers alike. Its seemingly small exterior supports a plethora of interior features such as twelve devices and high end GPU cards.

The HAF 912 embodies the rugged aesthetic and qualities of its brethren while remaining attractively priced. Its traits more closely resemble that of a mid to high-end case than that of other cases in its price range. The HAF 912 pays tribute to the legacy of HAF 932 & HAF 922 in ease of installation, high airflow, and compatibility with water cooling hardware.

FEATURE RICH STARTER CASE FOR ALL LEVELS
HAF 912 is the most compact solution in the HAF Series that still provides full desktop tower component support.
REMOVABLE / ROTATABLE HDD CAGE
The HDD cage can be easily removed to accommodate long high-end graphics cards. Rotate the cage 90 degrees to adjust your system airflow and cable management setup as you need.

4 out of 5 eggsSolid starter case

Pros: Good price, can fit larger GPU cards with the drive cage removed, moves buckets of air, looks ok, floor mounted 2 SSD cage and 2 HDD cage, takes optical drive with quick mount style lock.

Cons: Not as high quality feeling as I hoped, front panel a bit of a PITA to get off (top tab is behind the upper drive cages. Very difficuly to reach without taking both sidepanels off. Wish it was a bottom release style).
Cable management gromets would have a bit improvement to make sure you don't fray cables pulling them through. Edges are rounded off some but still worried me a bit.
Captive case screws would have been nice.

Other Thoughts: For the money, not bad. Will fit just about any mid-range build but if you are planning watercooling and multi GPU setups, might want to look elsewhere.

5 out of 5 eggsGreat Case!

Pros: Great Look
Fantastic Airflow
Sufficient Space Inside
Durable

Cons: Is a bit on the heavy side, however, this is not a big issue.

Other Thoughts: My main concern was space, and airflow when I was looking for a case to buy. This case was able to fit my needs and went beyond. The airflow is absolutely amazing, I have no doubts in my mind about my build overheating at all. The space was pretty close to not being big enough considering I had to fit a GeForce 770 GPU in their, but it still was able to fit with a bit of space to spare.

1 out of 5 eggsTerrible Fans

Pros: Descent case.

Cons: Problem I have.. Every single fan died within 1 year. That is absolutely ridiculous.

Other Thoughts: I dont think i would buy Anything coolermaster ever again.. Going to stick to Silvetrstone from now on

5 out of 5 eggsbest case for the price

Pros: Big, comes with fans and it looks decent.

Cons: minor things like not painted inside and has no usb3.0 headers and such.

Other Thoughts: The cons are not even cons considering this case is only 54 dollars. USB 3.0 can be reached in the back if your mobo supports it. I don't need a painted interior either. It is super easy to install parts into. Does not have the best cable management but like I said this case is big and you can make it work.

5 out of 5 eggsExcellent case

Pros: You get cable management, plenty of space for a video card, and a rotating HDD cage for an entry-level price. Coolermaster includes excellent documentation to help with the setup process. The aesthetics of the case are top quality.

Cons: You really can't go wrong with this case, it is designed with gamers in mind though.

5 out of 5 eggsGreat case!

Pros: Big case, Lots of airflow, looks great, lots of room, plenty of optical drive bays and hard drive bays. I have 4 hard drives in raid, still have room to slap an ssd in it if I want. Looks beefy, the 922 and 932 are too freaking huge in my opinion. They are great cases too though. I have built over a thousand custom built pc's and this is the one I personally use in my gaming computer. I bought a a big blue fan and installed it on the top of the pc. I bought 2, blue 12" cold cathode lights and it looks fantastic! Goldie locks and the three bears " Not too big, not too small, it's just right"

Cons: No clear side panel

Other Thoughts: They may have this option, but allow a clear side panel upgrade? It's not that big of a deal though. The Half 923?

3 out of 5 eggsIt's an OK case

Pros: The price. Great for a budget build!

Cons: When I bought this back a year ago it did not come with the right motherboard screws. The standoffs needed a finer thread. I ordered some and took care of the issue. A little frustrating when you have all the components, but a simple issue henders the build process.

Other Thoughts: The cable management is a little hard, but you can achieve great wiring with a little patience. The case was used in my first build and now I'm using it again for a second build. Due to the fact I didn't have enough money to replace it, but eventually I will.

2 out of 5 eggsMore of the same

Pros: The case is wonderfully designed and was very easy to use (exceptions below). The interior is roomy, and there is enough drive bays for anything you can possibly imagine.

The air circulation in the case is outstanding. If you plan on overclocking and using aftermarket cooling solutions, this case is for you.

Cons: Nice case for the money over all. There are a few issues with it, that must be addressed. My main "beef" with the case is the quality of fans provided. Within ONE DAY the front case fan started making ticking noises. The sound is considerable, and distracting. This will be the second HAF case with this type of problem. (my 1st being the 932) The front of the case will only accept 120MM fans. This is just a bad design, as all COOLERMASTER really needs to do is punch a few holes in the sheet metal. -1egg for faulty fan. (sounds like a card in bicycle spokes. checked it for clearance, the noise is coming from within the housing itself, not from the blades)

I will never buy a coolermaster fan because of this flaw. >ever<.

The perforations all over the case lead to structural issues, and the case is prone to warping.

Finally, the interior SSD bay is a piece of junk. It does not even line up with the holes drilled for it, and looks like someone stepped on it. That type of quality control is garbage. I should not have to use pliers to bend hardware into shape. - 1 egg

The "rapid release" on the 5 inch bays is useless, as it fails to hold a CD drive still enough to prevent rattling. I just removed it and used screws.

Finally there is a sharp edge on this case that gave me a significant cut, and it was near one of the wiring cutouts. I am glad I found it with my finger instead of with a power cable. -1 egg.

Finally, the rubber grommets on the back pop out with little provocation but are a beast to pop back into place. Expect a fight if you plan on routing cables through them.

Other Thoughts: Overall, if you can get this case for 40-50 bucks, it is worth it. Expect to purchase at least an extra 120MM fan. I am just tired of the poor quality control of CM products.

Manufacturer Response:

I apologize your HAF 912 is not working correctly as we can replace the defective fans through our CM Fanzone along with your purchase invoice and serial number at the link below as a Parts Request. We can also discuss your concerns through Live Chat, Phone and Support Ticket.

I look forward to your response.

5 out of 5 eggswonderful

Pros: it looks pretty awesome in person. This is the first time building a pc and im very very happy how everything came out.

Cons: the only issue i had with this is the grounding mounts it wasnt staying on the case so when i put the motherboard in and tighten it down it made this squeak noise and it was stripping it but all in all love the case
