    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 Great product with a few minor flaws!

    Pros: - Very large case with lots of room for the motherboard, graphics card, CPU fans, and RAM
    - Numerous bays for hard drive expansion
    - Two fans included
    - 4 additional fan mounts to keep air moving
    - Red LED indicators on the front of the case inadvertently matched the colors of my GPU and motherboard LEDs. Hooray for coincidences!
    - Looks awesome. Seriously.

    Cons: - Included tray for SSD is made of plastic and is difficult to work with (ended up using the metal tray that came with the SSD so no big deal overall)
    - No rubber grommets for the internal wiring ports (not sure if this is a big deal to most, but I would have liked them)

    Bottom Line: I bought this case for my very first computer build and I couldn't be happier. I bought fans for all available fan mounts but ended up not using the side port mount just so I would have a little way to get a glimpse of the computer's innards after assembling it. I was working with a fairly tight budget on this build so having a rebate available made this already affordable and awesome case that much more affordable and awesome. Highly recommended for beginners like me!

    4 out of 5 eggs

    Pros: -Nice design
    -Lots of space for HDDs and SSDs
    -Has front and bottom filters
    -Comes with 2 120mm fans

    Cons: -No filter on the top grating no the side, expect lots of dust
    -The feet are low quality, if you move your pc alot expect them to be lodged out

    Bottom Line: -Upon further research there are better cases out there, however I don't regret purchasing this case

    3 out of 5 eggs Poor exhaust vent / fan mount placement

    Pros: -Looks nice, no stupid plastic window.

    -has a spot for fan on the top.

    -Somewhat configurable.

    Cons: -The rear exhaust vent sits too high. You cannot install a liquid cooling radiator on the rear exhaust vent if you've got a large fan on the top. I bought a Cool Master 200mm case fan for the top, and it interferes with the Corsair liquid cooling kit I got for my CPU. Other cases provide more vertical space between the top vent and the rear vent.

    -most drive bays are riveted in, cannot be removed. Drive bays are split into 4 sections: three sections for 3.5 inch drives in the front, and one section for 2.5 inch drives on the bottom. I have no optical/disk drives, only an SSD. I would like to remove all 3.5 inch sections and move the 2.5 inch section forward. That is not an option. The middle 3.5 inch section can be removed, and the 2.5 inch section can be removed and mounted in place of the middle 3.5 inch section. I'm left with a bunch of empty drive bays.

    Bottom Line: -would not buy again

    -decent case if you don't plan to add lots of fans

    -I still haven't finished assembling my computer, got so frustrated trying to install my cooling that I had to write this review. Going to have to mount my radiator on the front, or put the fan outside the case.

    3 out of 5 eggs Ok case for the money

    Pros: Owned for about a year. can hide cables easily enough, fans it comes with are very quiet. Havent cleaned it since I bought it and the inside still looks great. Hardly any dust buildup on the electronics, really only where fans blow out from and thats easy to clean.

    Cons: My main knock on thia case is the flimsy power button that broke on me after about 8 months of use. Also the fan cables it comes with were too short and had awkward routing for my motherboard and gpu combo. The covers for empty peripheral bays arent a very tight fit and easily get kocked inside the case, but that isnt a huge deal.

    Bottom Line: For the money it is an OK case but not perfect. I upgraded to a more expensive case after the power switch failed.

    5 out of 5 eggs Easy to run cables, easy to install components.

    Pros: I've been building machines for the years and the HAF series from Cooler Master are some of my favorite cases to build with. This one was no exception. The drives are easy to mount, the cables have good corridors behind the motherboard so they are easily hidden, and the case has excellent cooling.

    Cons: I have seen it claimed that you can mount a 240mm radiator to this case. You can, externally on the top. This does not work with AOI units as there is no way to route the cables without removing the pump which you should NEVER do with AOI units.

    I originally bought an Arctic Cooling Freezer 240 for this case but swapped to an Air cooler after realizing this.

    4 out of 5 eggs Excellent internal setup

    Pros: With six 3.5" drive bays there is room for raid. The drives slide into the bays using plastic runners that press into the drive screw mounts and lock in position using spring loaded tabs. With the drive bays mounted left to right, cables are accessed from the right side panel and easy removal from the left side panel. Never have to fight getting tangled up inserting and removing drives. Front fan placement flows cool air over the stacked 3.5" drives. Mounting the power supply on bottom gives it cool air all the time (but don't put it on a carpet). The entire m/b is exposed and free of obstruction, lots of room for cpu coolers. Lots of punch-outs to secure cables with wire ties. If I used it, the arrangement for liquid cooling would be neat as well.

    Cons: I think it was a mistake to replace the two USB 2.0 front panel connectors with one USB 3.0 and one USB 2.0. Each of those internal connectors use both channels but provide only one output each. I'd rather have had the two USB 2.0 on top and used the lower 3.5" faceplate cutout in the lower 5.25 bay with a two port USB 3.0 for 4 total outputs.

    Bottom Line: There may be other excellent cases out there, but inside this is the most spacious, clean looking, ease of use case I have ever worked with.

    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.
