    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

    Cooler Master HAF 912 Mid Tower Chassis

    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 and high end GPU cards.

    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.

    HAF 912 is the most compact solution in the HAF Series that still provides full desktop tower component support.
    The HDD cage can be easily removed to accommodate long high-end graphics cards. Rotate the cage 90 degrees to adjust your system airflow and cable management setup as you need.

    5 out of 5 eggs best buy under 100$

    Pros: roomy enough to take massive video cards and hsf and still have room to work in. sturdy construction. easy to mod. great airflow with a few cheap fans

    Cons: no usb 3.0, bottom hard drive cage not removable unless you cut the rivets

    Bottom Line: removed bothe the hard drive cages and moved my 3.5" 1gb standard hd into the 5.25 bay to open up airflow at the bottom front of the case.. with 3 relatively cheap fans (2 in, 1 @ front and 1 @ side, 1 out @ top) this baby has plenty of airflow

    Pros: Great airflow and multiple fan placement options. Cable management is decent and although there are no rubber bushings it didn't have any sharp edges to contend with.

    Cons: None

    Bottom Line: Have used this case for 2 builds now, running as many as 7 fans but still nearly silent. Best case for the money, whether it's a budget build or performance this case works great.

    5 out of 5 eggs Great Case

    Pros: Lots of room to work. Comes with tons of extra hardware. Cable management was a breeze. No sharp edges to cut yourself on. Front panel wires are a good length.

    Cons: None.

    Bottom Line: I highly recommend this case, easily in my top 3 cases from here on out. I am not sure how well the 2 stock 120mm fans would have worked, as I immediately upgraded them to 2 200mm fans.

    5 out of 5 eggs Good Budget Case, Excellent Bang for Buck

    Pros: A good-looking case (in my opinion) with excellent air flow and plenty of room for large graphics cards after the removal of the upper HDD cage which still leaves room for two 3.5" hard drives. Comes with two 120mm fans, one front and one back, both work well and are fairly quiet. The front is entirely mesh which allows air to flow through the case uninhibited and keep the components cool. The motherboard sits elevated from the right side panel allowing for easier cable management by running them behind the motherboard. I was able to easily build my rig which includes a large graphics card (Sapphire Vapor-X R9 280X Tri-X) and a non-modular PSU (Rosewill ARC-750) without much trouble.

    Cons: No front USB 3.0 ports, no side panel window, front audio port was DOA on my case.

    5 out of 5 eggs Deserves the 5 egg rating

    Pros: This was my first computer build, and it was incredibly simple, and works really great! And I'd like to give some credit to this case!

    -High air flow
    -Lots of space
    -Looks awesome
    -Solid Construction
    -Lots of included hardware for versatility and expansion
    Was on sale for 55$, but I would buy again full price if needed

    Cons: I had some intermittent issues with the front usb and audio jacks, but I suspect something got bent from someone tripping on a plugged in cable. Usually giving the cord a wiggle restores functionality

    Bottom Line: I bought a 4 pack of Cooler Master fans with a Fan controller which works great to keep the fans low when browsing the internet, or crank them up for extensive gaming

    I set up the fans as the picture shows under the product overview Intake is front and side, exhaust is rear and top.

    I definitely recommend to anyone. Whether its your first budget build or an expensive rig
