Not a bad case, but an aging one sold on reputation at a price where the 207 and Frame 4000D are strictly better. Buy either of those instead.

Otherwise, I have liked prior Corsair cases I've used and am considering replacing my current case with either the 4000D or 5000D case just to have easier access to my front filter for cleaning. My current one, I have to pull it to a point it hangs over the edge of the desk in order to get my hand underneath the front panel so I can yank it off to get to the filter.

It goes without saying that the 4000D has hit the sweet spot for many thanks to its excellent airflow and hardware compatibility. This new version truly takes things up a level with more perforations, the Infinirail fan mounting system and loads of modularity to refine exactly the system you need.

This Frame case has me very intrigued, I must say, I have the 4000D airflow and found many negative reviews on it to be BS. Also very cool to see you building with the Stealth Ice board - that's my board, but rarely see it since it isn't sold in the US (I special ordered mine from EU). LOVE this board, I've heard they're putting an X870E version out too.

Just got this case, it's quite nice especially considering the price. The only thing I wish it had was a dust filter for the top panel. Everything else is great and pretty straightforward to install. I'm probably going to add some sound dampening material to the back panel and base as it's a bit louder than I'd like but hardly deafening.

I'm looking at getting the 4000D Airflow, but I'm looking to put 3 fans in the front for intake, 2 on the top for Exhaust, and one at the back for Exhaust. Hoping the Temps would be a lot better that way, as my current cheapo case has dang near the same design with the mesh front, but has 2 CDROM drive slots on the top, which are unused.

T The Honest Verdict Article
The CORSAIR FRAME 4000D Modular Mid-Tower ATX PC Case is a genuinely interesting product at this price point, and the modular angle isn't just marketing. The InfiniRail system solves a real problem with fixed fan mounting positions. The swappable I/O panel solves a real problem with front ports becoming obsolete.

Other than this key downside, the case executes nearly flawlessly on its thermal goals for its price and its price does let it get away with a lot of other tiny annoyances. For example, although it supports larger, we recommend a 150mm-deep power supply as the maximum size to help with some of the cable issues.

The 4000D Airflow is an absolutely great case, I just wish I would've gone for the 5000D for future water cooling. The 4000D "can" have a full liquid cooling loop in it, but then it'll be packed to the edge, 5000D has more room for Reservoirs and tubing routing.

The Corsair 4000D excels in providing exceptional cooling performance. Its high airflow steel front panel designed with wide ventilation channels ensures that your components stay cool even under heavy loads. The case supports up to 620 mm or 440mm cooling fans, and it can accommodate multiple radiators, including a 360 mm radiator in the front and a 280 mm radiator on the top.

This is so far the most detailed video about this case. I recently got this case, absolutely love it, but I also have a few issues, not game breaking, but you can clearly see not enough thought was put into them. 1. The panel GPU bracket, probably only for the 50 series as my 3060 triple fan GPU does not reach that bracket, even when the panel was shifted closer to the motherboard.

I bought this case and I like it quite a bit. I was using a case that was built more for aesthetics than performance, and I saw great improvement in terms of thermals. Between the daisy-chaining and the modular theme of the case it was far and away the easiest build I ever completed. That being said, I really did not like the Infinity Rail in the front panel.

Good review and agree with you, the original 4000D was one of there record selling cases, I can see why they are trying to incorporate the 4000+5000 series into one and price point makes sense. If guess a 240mm radiator at the top on the original was limiting for the higher end CPU market and people upgraded to the 5000 series.
