  • FRAME Modular Case System The revolutionary FRAME system gives new meaning to the word customisation. Want to upgrade the motherboard tray to billet aluminum? Want to swap out your front I/O panel for more USB ports? Now you can. A case that can change and grow with your needs (or just your mood). The options are nearly limitless.
  • CORSAIR InfiniRail Fan Mounting System This steel multi-point mounting system offers unmatched flexibility in front and roof fan configuration. Simply slide the rail to mount fans up to 200mm (140mm in the roof) wherever you like, ensuring targeted airflow.
  • Clean Lines or Turbo Cooled The internal side panel near the motherboard tray can be used as a cable cover for clean cable management, or you can remove it and mount fans to the side for increased cooling potential.
  • 3D Y-Pattern Airflow Panel Optimized for high airflow and minimal restriction, the steel front panel is perforated in three dimensions with a Y-pattern that provides a low-obstruction path for cool air.
  • Dual 360mm Radiator Support Take your cooling to the next level with three mounting locations for 360mm radiators (front, roof, and side). Mount up to twelve 120mm fans simultaneously to keep cool air flowing in and hot air exhausting quickly and efficiently.

    • Easy to work with, quiet, great airflow and highly customizable
Color: Black
A wonderful and easy to use modular case. Stylish and easy to clean and plenty of room to tweak and make changes as you upgrade your build. Want to go from 120 to 140mm fans you can even up to 160mm fans. You can even swap in the included side panel for 3 additional side fans for more airflow. Truly a pc gamers dream for making their own build. <3 Super quiet and sleak just a perfect case thank you Corsair 😊 ... show more

    • Beautiful, durable, and great airflow
Color: Black
Beautiful case that has great airflow and opportunity for lots of fans! This case looks clean with and without RGB, it’s made of durable metal and excellent quality. The noise level is minimal with arctic fans, and has plenty of room for large GPU’s

    • Good Sturdy Case
Color: Black
I bought my fiancée a gaming computer for Christmas and this is the case I got for his build. It’s nothing crazy but it’s built sturdy and easy to work with. We’ve moved twice with this thing, so I can say quality is a good and it can handle being moved if you need it to. It seems to have good airflow as we were living in a bit of a hot space for a while and it didn’t have any overheating problems in 80ish degrees. The noise level is average on the quieter side. You can hear it working at times. ... show more

    • Solid First-Timer Case
Color: White
Roomy and easy to build in. The front, sides and top panels can all be removed, and the front panel includes a magnetic mesh panel that can be quickly detached and cleaned. My only complaint is that the InfiniRail system was confusing as a first time PC builder. It's a handy feature for enthusiasts with fans/radiators of different sizes, but for a first build it largely over-complicates fan/radiator installation. Other than that, the case offers a largely pleasant building experience. ... show more

Great overall. You can even fit 3 140mm at front if you try a little, with 360 radiator at top. Can’t wait to see future case accessories and parts. Things to beware: The PSU shroud is blocking the 200mm fan at lower front position. I had to cut a piece out to fit 2 200mm fans. The top panel is very very flimsy from the new cutout pattern, beautiful design but deform easily and I have cats. ... show more

Great quality and easy to work with. Looks amazing. Very happy with this (Frame 4000D - white) case. Only downside so far is my new GPU (Sapphire 9070XT) isn't in the right spot for the adjustable support peg. It misses in the normal slot, and hits the fan when using the extra part that it comes with to put said peg closer to the mobo. ... show more

    • Awesome case and updated version of a classic.
Color: Black
I’ve been struggling to find a case that I liked aesthetically and functionally that provided great airflow. Once I found this case the search was over. It is solid and I love the modularity of the new frame model and design. It is pleasant to build in with plenty of room. The only complaint I have of it is that the space for cable management is limited but that is just one negative of this awesome case. ... show more

    • Great Concept, Good Design, Flimsy Steel
Color: White
The Good: A lot to like about this case. Mostly the “frame” concept and ability to modify the case to fit your needs or wishes. There are some really interesting options available. Options and flexibility increase usefulness. It is clear that a lot of thought went into the design of this case. I like the, mostly, lack of plastic parts. The case is very easy to build in. I like the clean unobstructed airflow provided by the front fan rail mount system for 120/140mm fans (the rails do not disturb the airflow like most cases do). And I like the ~5/8” gap between the dust filter and the fans (it improves fan performance and acoustics). Some good engineering here that often goes unnoticed by reviewers. I like the nylon dust filter in the front and bottom because it outperforms the currently popular ~1mm holes punched in a plastic sheet or front panel that let too much dust through. The filters are very easy to access and clean. I like the white color because black shows every speck of dust or dirt. And I like the wood front grill. The Bad: The steel used is thin and weak. It works; but it bends, wobbles, and does not instill confidence that it will endure over the long term. In fact, my case arrived with a slightly bent side panel and I had to return it. Weak steel can perhaps be accepted in a budget-ish ~$104 case. But with options this case can run $200 or more; and weak steel is definitely not acceptable in a premium-priced case. The strongest panel on this case is the glass panel… The Wishes (for new options or the next generation): Better steel! The support of three 140mm fans in front (they outperform 120mm and 200mm fans); it appears the physical space exists but it just wasn’t an objective. A solid top panel option i) to ensure the airflow from the front fans actually gets back to the CPU/GPU and doesn’t leak out the top, and ii) to protect from liquid spills or dust/dirt dropping from above the case. Lastly, a 2-Drive HDD cage for the bottom drive location. The Summary: The “frame” concept is a great innovative idea from Corsair. The implementation of this idea very good in many areas; but the flimsy steel undermines all the good design work. I hope they continue to invest in it because it has the potential to become a great case. ... show more
