Features    [ Edit | History ]

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, high end GPU cards like the ATI Radeon HD 5970 and the NVIDIA GTX 480, large CPU coolers, two 200mm fans, and six 120mm fans.

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.

great product
case was slighty dented but that was due to shipping

Experience: 4 Months
 Verified Owner
Works as intented
cheap but thats also a pro because of price.
Needed a good case on a budget and this thing delivers. 4/5 would purchase again.

Experience: 7 Days
 Verified Owner
Fantastic case for build for my son. Can five no faults at all. Love the 2.5" mounting cage for ssds. Great price
None at all
Said it all already. This is an awesome case at a great price for a gaming build. Added 2 200mm green fans to top and front. Just trying to figure out what to do with separate led switch leads now. I don't like to hook the switches up and leave then dangling inside. No fan controllers with 2 pin led on/off control anymore so wire them both to a single switch.

Experience: 10 Days

-Provides great airflow
-Good cable management
-Plenty of space for fans
-Removeable drive cage for larger GPU's
-Motherboard posts were difficult to screw into (I might just suck)
-Stock fans aren't the best quality
This case is definitely good for the price. It provided everything that I was looking for. If you are going to be buying this case, BUY YOURSELF CASE FANS. While this does come with two built in fans, they aren't very good. Invest in some more fans.

Experience: 5 Days
 Verified Owner
Great case! Well made, with plenty of room. Easy to install the MOBO and multiple fans. I will be buying this or something similar for my next build too.
As others have said, no front USB 3.0, but really that's a minor thing.
Good, solid case. Great value for the price.

Experience: 1 Months

-Crazy amounts of airflow.

-Tons of room to work with.

-Convenient side facing drive bays made
HDD installation simple and easy.

-Looks like it could survive a bomb blast.

-Cable management built in.
-Edges are a bit sharp on the case doors but not a big deal if you are careful.

-No front USB 3.0. Not a big deal if you have 3.0's on the back as you usually wont need a 3.0 on the front unless you are transferring files to and from a jump drive a lot.
I am overall very happy with this case. The cable management behind the HDD bay and Mobo mounting plate made the inside of my setup look like it has no cables in it at all. I would recommend to anyone looking for a sturdy case with tones of airflow and room. The HDD bays are also so easy to install and remove a 3 year old could do it in 5 seconds.

Experience: 4 Days
Solid Case
Inside is very clean
Lack of front USB 3.0
This is an awesome case, the only drawback is the lack of USB 3.0. I'll probably just purchase a front USB 3.0 bay. Other than that, very nice case with excellent design and very quiet.

Experience: 4 Months
 Verified Owner
- Affordable price
- Solid build quality
- Great fan layout
- Plenty of air flow
- Easy to clean fan screens
- Lots of room to work in
- Bottom mounted PSU(my first case with this)
- Great cable management
- Removable HDD rack
- Tool free HDD
- None
I really like working with this case. There were no issues finding the room to fit everything I bought.

Some would like to have the front USB 3.0 and I'll admit that would be a great addition, but for me the USB 2.0 is just fine, as the only thing I plug in there is an Xbox 360 controller.

The look of this case is very utilitarian but it has more than some of the more expensive cases on the market. The build quality is very solid and the price can't be beat.

Experience: 20 Days
 Verified Owner
Cheap, Decent Build Quality, Has quite a lot of room.
No USB 3, I hope that they do a revision of this Case as it is the best bang for the buck case on the market in my opinion.
I enjoyed building in this case, it has a lot of the features that a higher priced case would have, with decent amount of space for cable management and longer video cards. I recommend this case for almost all of my tight budget builds as I believe this case has a ton of features for the price, generally around $50. I would love to see this case get a new revision where they make minor changes like adding on board USB 3, etc.

Experience: 1 Days
Great low price
Simple to build
Lots of room and options to the case
I just can not complain about this case. It may not be flashy, but I like the placement of everything inside. I like that I was able to remove some of the drive bays and relocate the 2.5 inch drive bay there. That gave ample room for the cables and everything came together nicely.
