    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 Value but Missing Screw

    Pros: Plenty of features
    Lots of room for expansion and fans
    Easy to use
    Reasonable Price

    Cons: None so far, other than a missing part.

    Bottom Line: My case was missing one of the thumbscrews that keeps the side of the case attached to the rest. The instructions for the case clearly display two screws, but there is nothing but an empty hole where one was supposed to be. The missing screw didn't turn up loose in the packaging or in the rest of the mounting screws that came with the system. I can almost certainly get by without it but it gives me the impression that Cooler Master quality control is not that good.

    5 out of 5 eggs Amazing variety and cable management

    Pros: --A large variety in drive bays including space for an ssd or two,
    --Hard drives can be equipped with side pieces to mount beautifully in the bays, no screws needed.
    --comes with 2 120mm fans, and has great expand ability and many cooling options available for this case
    --front bay includes a coverwith a smaller indent that can pop out for a smaller card reader, and fits my old card reader sturdy and like a glove.
    --LED fans in this case really shine!
    temps are 75% better than my old 7 year old dell case with my semi custom internals for that one very impressive,.

    Cons: i cant think of any, this case is just amazing.....

    Bottom Line: Being my first new case, this is by far the best i have ever had, the temps are just freaking amazing, i fully recommend 69/69

    4 out of 5 eggs good case

    Pros: the case is built amazing i love the case
    plenty of space for a smaller graphics card (i have the sapphire hd 6970 in it and it takes up the bay)
    for the money its awesome

    Cons: case is small for big cards
    face plate sucks
    face plate sucks
    face plate sucks
    i had the case for about a month before the face plate mounting pins broke so now i have a face plate that holds on with a pin and needless to say the face plate falls off a lot, let alone the face plate is to small for a standard size dvd drive with out pulling on the face plate for it to slip around it. the airflow isnt great with any graphic cards 10.6" x 4.5" i have a card this size and it touches both ends of the case, i run the pc with the side off just for it to breath

    Bottom Line: its a good starter case for the price it has treated me very well i like it but after a year and some modifications and realizing its time to get a bigger card and a bigger case with better airflow im going to let it go.

    5 out of 5 eggs Great Case for Any Build

    Pros: A great size for about anything you would want to build. Ample room for any cooling setup. Not a bad look either. Comes with sufficient accessories to complete the build. Good pricing point especially when you can get a rebate or find on sale.

    Cons: I've completed two builds in this model case over a four-year period. It's time to put USB 3.0 outputs in the front.

    5 out of 5 eggs popular case for a reason

    Pros: -great room for cable management, definitely enough tie-down spots.

    -easily removable/Turnable HDD bracket was a huge plus, even though it did fit my MSI Gtx 970.

    -very clear instruction manual, I was a first time builder and definitely appreciated this.

    Cons: Can't think of anything.

    Bottom Line: There's an etched table inside the case listing Motherboard types and the mounting screw locations for each. It was incorrect in leaving out the "G" location for ATX.

    5 out of 5 eggs Great case

    Pros: Plenty of room, low cost, good air flow, well made, solid.

    Cons: The only con I have to say about the case, is I wish I was able to do better cable management. But that more then likely my fault.
