Corsair is a company that does not need much of an introduction - they are one of the world’s most reputable manufacturers of PC components and peripherals, with a vast range of products for all wallets and tastes. One market section that Corsair is highly active in is that of PC cases, with the company frequently releasing new designs and currently marketing dozens of products.


Today we are having a look at one of Corsair's most recent releases, the Carbide 400Q. The Carbide 400Q is not formally designed to replace or compete with any of the company’s previous models, but it feels as if it the spiritual successor of the Carbide 330R. The midi-tower case is designed as a financially reasonable solution for users that want an refined yet simple and quiet system. We are having a close look at the features, quality, performance, shortcomings and value of the Carbide 400Q in this review.

Packaging & Bundle

Corsair supplies the Carbide 400Q in a sturdy brown cardboard box. The monochromic artwork is simple and based on a schematic of the case itself, with a short description of the case printed in several languages. Although it is not much to gaze upon, the sturdy box and thick Styrofoam slabs provide more than good protection during shipping.

Corsair barely supplies more than just the basics alongside with the Carbide 400Q. The bundled items are just a user’s manual, black mounting screws and a few short cable ties.

    VERY POOR CASE !!!!! (400Q)

    That's very worrying. When did this problem start? Do you have an idea what might have caused it?

    I would also like to chime in with a piece of criticism: The latches of the front panel are just extremely prone to breaking off. In fact, I saw a Corsair employee manage to do it at a Corsair booth the day after I did it myself! How did this make it through quality control!?

    Okay, for those of us non-techies who very rarely get inside their own computers, let alone pry and snap things inside to get a better view, the direction. . .

    "To remove the two plastic covers that separate the PSU and HDD area from the rest of the case, the HDD cover has to come off first, then the PSU cover."

    means absolutely nothing.
    I can see the one piece (HDD) on the desk and the second piece (PSU)
    still attached to the inside of the main box... I know which one comes out
    first just by looking at the picture.
    I see the snap-latches that need to be pushed in order to get the covers out.
    The HDD latch has a cover of some sort on it that cannot be pushed, slid, or lifted...
    I can feel the pins under the chassis... once I get them to a position where I can pull the front up from the bottom, do I yank it up... push something else... or slide it...?


    I've considered myself a logical person for many, many years...
    but this box has me stumped...
