    This is a great case! So easy to build in, and everything is incredibly organized. I think the most important feature though is the thermals of this case. The case is designed for breathability which keeps all your components very cool. I did have an issue with the fan sucking the front mesh into it and creating a really annoying noise, but I removed the mesh and put it back a few different times and somehow it went away.

    Love this case so much I put my 2nd build in the same black airflow looks amazing awesome temp very highly quality materials and build. The smaller size gives it much more modern look than the 5000 and wayless wasted space some corners are tight but I found it fine to work in. I recommend Corsair RGB fans they look amazing worth every penny I spend half my day memorized.

    I used this case for my first ever PC build. It was very roomy and easy to work with. Different components remove or slide around easily, making it simple to adjust it to your needs. The dust filters are easy to remove and clean, making this a perfect case for a dusty environment. The two included fans are ok and get the job done, but I did supplement them with a couple aftermarket fans to help cool my components.

    This was my first time doing a case swap and i love how much more space and air flow this case had compared to my HP omen. It also has some cool features and great cable management options. It also has alot of room for additional fans. I added 3 RGB fans to the front with ease and one more fan at the top of the case.

    Having worked with many people to upgrade or build new rigs I can say this was without a doubt one of the best cases I have ever worked with. Cable management was easy, components had plenty of room and airflow is great. The case also looks amazing with some subtle lights to accent it.

    Really nice cause, came with plenty of screws, straps, etc. fans that it came with I wouldn't recommend. I got it for $104+ and saw the price drop a few weeks later. There's probably better options out there. I actually wanted a Fractal North XL but it would have taken forever to arrive and I didn't want to wait to long. This case has really good airflow.

    Wonderful case! Great airflow and decent size case. Bigger case from my prebuilt computer. My last case was so small, I couldn’t even fit a new PSU in my old case lol. Corsair rm750x didn’t fit in my prebuilt but in this case it did.

    So I built a very basic PC from scratch, my old one was too small for my new ATX motherboard i had. I just wanted to play starfield. Super easy settup. Depending on what power supply you get, cable management may be a bit messy but i am really happy with my purchase. I have no extra fans currently, without RGB fans it is a simple, beautiful case, not flashy. With RGB Fans I am sure it will look even more phenomenal. There is an air vent on top that helps with ventilation, with a magnetic mesh style cover that goes on top to keep dust out for when you dont need to let heat out. For the price you cannot miss on this. Seriously was well worth it. Definetely planning on upgrading in the future and this case will be the constant.

    I really like the minimalist all black design, the tinted glass side panel is also really cool. The inclusion of velcro straps for cable management was a nice extra as well.

    Optimal Airflow and Elegant Case

    This case is one of the best cases in its class. For the price, it offers excellent cable management, optimal airflow, and aesthetically pleasing to the eye. I'm rocking an Intel 9600K CPU with a 1660 super GPU and multiple M.2 SSD. I have installed within the case, 2 140 mm fans and 4 120 mm fans as well and my temperatures are with normal use 25-28 degrees Celsius and with the most extreme games only ever getting to 45-50 degrees. This case rocks and is a highly recommended case from not only myself, but also from many tech reviewers out there. Only reason I gave it 4 stars is because the product came damaged, probably from handling, but luckily I reached out to Corsair and am currently being sent the pieces that came broken. Seems like the plastic isn't as durable as it may appear.

    I'll be honest, I was a bit conflicted with getting either this product or the 4000x with the tempered glass but I'm really glad I went with 4000d. It looks amazing with all my pc parts together and more than enough space compared to an average mid-tower case. The airflow in this product is superb and I would recommend this to anyone that prioritizes pc cooling performance.

    This is one of the best cases you can get at best buy. Amazing air flow keeping all of your components cool, depending on your air flow pressure. Easy to work with and you can front mount a 360 rad if you choose to do so. I'd recommend doing a top mounted 240 rad so you don't risk fast liquid permeation.
