    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

    4 out of 5 eggs Review of Cooler Master HAF 912 - Mid Tower Computer Case with High Airflow, Supporting up to Six 120mm Fans and USB 3.0

    Pros: - Very affordable cost from Newegg. Also currently has a rebate available (Aug. 2016).
    - Roomy. Installed an ASUS Z170-A motherboard without any issues (plastic cover/shield on ASUS I/O panel is an issue with other cases.)
    - Dust filters (HAD 922 doesn't have them.)
    - As advertised, numerous fan options.

    Cons: - No thumb screws on back cover (would have been nice (like HAF 922)
    - Would have been nice to have a second pre-cut 3.5" slot in the 5.25" cover.

    Bottom Line: - If I had a need for another case, I would buy this one again.

    4 out of 5 eggs Solid for Price

    Pros: Solid case. This is my second one. First one bought years ago. Got this one at a low price (AND a rebate too!) probably as it is at end of product life and only has USB3.0 connectors. That said, with the rebate this was a great case for an upgrade for my son. Definitely would consider (newer) Cooler Master cases again.

    Cons: Obviously a very solid product but at end of product life. This means no USB3.1, not as many connectors as you would like nor as many fans. Not much on top of case in way of connectors and ports. This is an older case and, of course, it shows. But value for money if you are not looking for high-end gaming case.

    Bottom Line: Still would recommend for non-gaming applications.

    5 out of 5 eggs Awesome case

    Pros: Excellent cable management, sturdy build quality, plenty of room for upgrades and fans or even a water cooling system. Air flow has been great so far

    Cons: For the price it could have come with more fans, maybe some dust filter options. Honestly not too many downsides.

    Bottom Line: i have built a lot of computers for family, friends and myself and I have to say this is an amazing little case. sure it isn't the smallest but is great quality with plenty of room for cable management and tons of expansion options. I would recommend this case if you are building a serious PC and want room for addons and even multi gpu setups.

    5 out of 5 eggs Really good case for the money

    Pros: Plenty of room and customization option are a plus. I like the fact that side fan attach option is between cpu cooler and psu. I added a large CPU cooler and could attach a 120 mm case fan on the side. The case is solid built has 4 additional case fan attachment option. One of the best cases I have come across over the years.

    Cons: It served its purpose very well so no cons.

    5 out of 5 eggs Nice case

    Pros: Nice layout, easy to work in.
    Driver trays come with hardware to just slide in and lock the drives. No screws required.

    Cons: Only 2 front USB headers but that is pretty standard.

    Bottom Line: I have built a couple systems with this case.

    5 out of 5 eggs This is one GREAT platform to use for your next home-built PC

    Pros: The case is open and easy to work with. All hard drive bays are very accessible, and there is a cage specifically for 2.5 inch drives that mounts to the bottom of the case (it holds 2 drives).
    The power supply is mounted at the bottom of the case, which makes great sense from a power cord management viewpoint. I've never understood why desktop vertical case makers always wanted to put the power supply at the top of the case instead of at the bottom.
    The construction of the base is top notch. It is rock solid and has plenty of openings for fans, including some at the top of the case. The side panels on both sides of the case are removable, making access to all parts of the case easier.
    The hard drive bays use a slide-in system where you attach two slip-on rails to each drive and slide them into place where they lock solidly, but are very easily released for removal or repositioning.
    While there is no built-in USB/SD card front-panel slot arrangement, I did purchase a 3.5" third-party unit that I installed in the 3.5" bay that opens to the front, and that has been great.
    All-in-all, I consider this one of the best built cases I have ever used, and I would heartily recommend it to everyone. I'm a Cooler Master convert for the future.

    Cons: While I did compliment Cooler Master for placement of the power supply on the bottom of the case (and I still think that is a great position for it), there is a matter one needs to remember about that. I recently found my computer shutting down without warning. When I took the case over to a work area where I could set it on its side, I noticed that the power supply fan intake area was totally clogged with dust. I'm sure this was the problem that caused my power supply to overheat and force a shutdown. Once I cleaned away the dust from the mesh Cooler Master places over that fan intake area at the bottom of the case, everything is fine now.
    BUT BEWARE!!! CHECK YOUR VENTILATION PATHWAYS EVERYWHERE FOR DUST!!! This is a problem for all computer cases, not just this case, but as this is the first case I've had with a bottom-mounted power supply, I thought I would mention it here. It never occurred to me that this dust build-up was occurring, as the fan intake was out of sight on the bottom of the case. I'm going to calendar a six-month case cleanup for all my computers. It just makes good preventive maintenance sense.

    5 out of 5 eggs Very nice case

    Pros: I moved from a micro tower to this and it is great. The cable management is nice and I had lots of room to work with.
    Has room for six fans (120mm)
    Has a bunch of space for HHD/SSD as well as 5.25" external bays.

    Cons: None yet
