    Color Blind Manufacturer

    The person that assembled thias must have been color blind. I spent the better part of 3 hours trying to figure out why only the "reset" LED would come on when I plugged it in. I took the face off the front of the case, this after trying several ... Read more

    Quick Info


    • Limited Warranty period (parts): 1 year
    • Limited Warranty period (labor): 1 year

    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.

    4 out of 5 eggs Good case, needs more fans

    Pros: This computer case is a great size. Not too big, not too small and will house everything you need.

    Cons: The only problem I have with this case is the fact that it doesn't come with enough fans. It comes with a rear fan and front fan. That's it. No side fan or top fan. I'd have been much happier if it had a 200mm front and top fan, along with the 120mm side and rear fans. So I knocked one star off.

    Bottom Line: I guess the HAF 932 jaded me. It came with massive fans and was quiet.

    4 out of 5 eggs cool master case

    Pros: large enough case for most builds . good overall case design , did purchase 2nd one for another build

    Cons: had issues with water block - cant use a large radiator , very easy , fans in the way with back of case , had to modify vent screens to hold radiator . , could use small water system with no problem

    Bottom Line: I AM DISAPPOINTED , after system build followed instructions and sent in upc , there rebate form and my packing list with case model highlighted , they refused the rebate , no invoice copy , that shows cost or price of item . think I will try other maunfactures to see if they honor rebates .

    5 out of 5 eggs Lots of options

    Pros: solid feeling case, has lots of options for cooling,cool looking has many different adaptions for different size drives, has lots of form factors very versatile case.

    Cons: only thing is if you have a 200mm fan on top and cooling radiator in back with push pull setup both fans will not fit on inside but you can mount fan on outside and this case has nice rubber holes for lines to go through

    Bottom Line: very well thought out case

    4 out of 5 eggs HAF 912

    Pros: Good, solid case with great airflow.

    No obnoxious LED's to make it light up like a Christmas tree when powered on, which I prefer.

    Cons: No front USB 3.0 ports, but my motherboard doesn't have headers for those, so not really a problem.

    Can't get the front fan running because the cable is too short to reach my motherboard, and one of the molex adapters it came with didn't seem to work. Despite that, the whole system still stays reasonably cool when running games.

    Front 3.5mm audio jack sounds like demons trying to communicate with me, so I'm using the jack on the motherboard instead.

    5 out of 5 eggs First PC Build, Case

    Pros: This was my first PC build and I really wanted a good case for the money, this case definitely was the best choice!

    *Remove able hard drive cage allowed extra space
    *Enough space for cables that I wasn't squishing them against the back panel
    *Many cable tie down areas really made my first build more enjoyable haha
    *Came with 2 fans, although not the best it helps keep the case pretty cool

    Cons: None, I am super happy with this case!

    Bottom Line: This case really helped make my first PC build enjoyable by making the cable management not a nightmare.

    My System Specs:

    CPU: AMD FX-6300
    Motherboard: ASUS M5A97 R2.0
    RAM: Crucial 8gb 1600-DDR3 Memory
    Storage: Western Digital Caviar Blue 1tb
    Video Card: XFX Radeon R9 280x
    Case: Cooler Master HAF 912
    PSU: EVGA 600B

    5 out of 5 eggs great case for budget gaming build

    Pros: Has room for all the essentials for a gaming build. Exterior can be easily modified if you must have the window for viewing. Comes with pre-installed fans with room for more.

    Cons: No USB 3.0 or 3.1

    Bottom Line: Any decent motherboard will have your USB 3.0 & 3.1 but if not you can install them in drive bays. This is a great case so nothing really significant to complain about.
