HAF 912

Disclaimer: Displayed parts and accessories may not be included in the actual product package.


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.

      "Many cases I’ve noticed look as though they’re primarily designed to stand out, to be that centerpiece of your room. That’s great—a lot of them look awesome, and come with plenty of features. But that’s not our style. We wanted something functional and low-key, a case that would blend in and fade away. When considering our options, one of our biggest criteria was the case’s size. When you’re used to lugging around an 11-inch MacBook Air, it’s a little overwhelming to purchase something that you need a forklift to carry. What we found is the perfect compromise between size, functionality and looks: Cooler Master HAF 912."

      "Getting a Cooler Master HAF chassis for under $60 should be a big draw for budget minded users and the 912 deserves a spot on their short list."

      "Rather impressive case. By being a mid tower HAF 912 offers the same functionality and ease of installation as larger cases on the market. Smaller is better in this case as we found out. With support for latest video cards and some of the largest CPU blocks HAF 912 make a great case for any gamer/enthusiast."

      "For a mid-tower it is capable of comfortably stuffing a crazy number of hard drives and other hardware under the hood. Some of the clearances on the SSD's cage and the videocard were rather tight, but the engineers have solved that with removable hard drive cages. This mid-tower really does it all."

      "The added width of the case allows for larger CPU coolers, as well as space behind the motherboard for wire management. The included 2.5? SSD bay was unexpected and perfect for switching over to using an SSD. It would be extremely difficult if not impossible to find a better case at this price range. It really lives up to its name."

      "MSRP for the HAF 912 is $59.99, placing it in the bargain basement as far as costs go. With many of the recent mid-tower cases we've reviewed lately pushing the $100 mark, the HAF 912 offers a lot of potential for a very small price."
