Corsair Carbide 400C Mid-Tower Gaming PC Case Review

I'm just a small-time guy working a normal job as a physician assistant. My passion is building PCs and testing/reviewing PC hardware.



Today, I am bringing you my review of the Corsair 400C Compact Mid-Tower case. This offering from Corsair is one of their midlevel cases and brings a lot to the table in terms of features and upgradability. So, without further delay, let’s get started.

Corsair Carbide 400C Mid-Tower Gaming PC Case

I had my eye on this case for some time and I was ecstatic to see the really, really good deal being offered on Black Friday. Fry’s Electronics had this case on sale on Black Friday for just $64, which is $35 below MSRP. To sweeten the deal, Corsair also offered a $10 rebate and Fry’s gave free shipping. So the final cost for this case, given that there was no sales tax either, was just $54. I must say, it is a steal of a deal.

This case is part of Corsair’s midlevel range of PC cases in their Carbide series. The Corsair Carbide Clear 400C has been engineered to pack all the performance and expandability needed by veteran and novice PC builders into this beautifully compact case design. With the large, clear side window, you can put all of your components on display for the world to see. The case features Corsair’s Direct Airflow technology to keep your internals cool and quiet during even the most extreme moments of gaming.

The Corsair Carbide 400C case offers a one-touch side panel, tool-free drive installation, and three-point dust filter access. The side panel has a hinge and handle allowing easy access. For the building process, the side panel can be removed from the hinges giving you a substantial and clean area to build in. The case also features a power supply shroud which gives you plenty of room to manage your PC’s cables. The case offers plenty of space to build in, even in the compact design. There is room in this PC case for up to a 360mm radiator in the front, a 240mm radiator on top, and a 120mm radiator in the rear. You're able to quiet your GPU and CPU with liquid cooling. The Corsair Carbide 400C comes with two high airflow fans preinstalled: an AF120L, 120mm fan in the rear, and an AF140L, 140mm fan installed in the front. These fans allow extreme airflow to be pushed across your hottest devices without much noise while cooling.

The Carbide 400C’s direct airflow design provides an excellent path for cold air to get to the most heat intense components of your PC gaming build. Also, inside of this case, beneath the same power supply shroud, you have the option of hiding your 3.5” drive bays that will typically house your mechanical hard drives of which there is room for two of them. With the easy access dust filters on the front, top, and bottom, you will not have to spend much time cleaning the dust from your system that is bound to accumulate.

Overall Impression

So, how is it to build in this system? Well, fantastic if you ask me. I transferred all of my components of my Intel Core i7-7700K gaming PC over from my DeepCool Tesseract SW Blue compact ATX mid-tower case. I must say, the Corsair Carbide 400C was far easier to build in than the Tesseract and felt far sturdier. This was a nice upgrade from the budget cases I have built-in before. The transition from the Tesseract to the 400C was smooth and there was plenty of space to work with. I had many options when it came to cooling the PC. I placed my 120mm Corsair H60 All-In-One liquid CPU cooler in the front of the case at the top with the included Corsair 140mm fan below. I was able to keep my push/pull fan configuration with the Corsair H60 liquid cooler using the H60’s included 120mm fan and the 120mm fan that was originally in the rear of this case. I installed a Thermaltake Riing 12 fan in the top and another in the rear, both in exhaust configuration. Both of the Radiator fans and the 140mm fan in the front are in intake configuration. The MSI Z270 Tomahawk motherboard installed very nicely and easily. The power supply shroud was a welcome addition and made cable management a breeze. The case easily housed the MSI GTX 1080 Duke graphics card and the internal layout is very, very clean. All in all, this was a fantastic case with a lot of room to build in and will definitely support a lot of upgrades.

I was really impressed with the cable management in this case as well. My only gripe about this case, however, is the power supply shroud itself. It took some finagling but I was able to get it back into its original location and after that, the couple of other times I had to remove the shroud for cable management, the shroud slid right back into space without any issues.

Conclusion and Final Thoughts

The Corsair Carbide Series 400C case is a great mid-level gaming PC case option at the MSRP of $99.99 but at $54, it is a fantastic, over the top deal. The case was easy to build in and looks like a high end, enthusiast case. I can and will confidently recommend this case to anyone, even at $99.99. If you can pick this case up for less than $100, by all means, pick it up and enjoy your beautiful gaming PC.
