    One of the best air flows you can in 2026

    Excellent case for those looking for extra build room and superb air flow. The dual chamber is primed for cable management and a clean view from the front. The glass panels are sturdy and if you get it in white, your parts and RGB will be a show stopper. This is my second NZXT case ever and the quality is undeniable. I highly recommend this case.

    Fantastic case - tons of benefits

    A genuinely fantastic case, it's huge but is absolutely worth the price. It comes with 3x140mm stock intake fans and 1x120mm stock exhaust. It has open support on both the top and bottom radiator for up to 3x140mm fans respectively, is a dual chamber meaning cable management and clearance headroom is extremely easy. It's access and latching are also extremely friendly, featuring double take magnetic + non-detachable screws that are incredibly easy to use. If you want a good dual chamber large case for extra fan support or easier cable management, this would be my ultimate recommendation

    Wonderful Case, Very Easy to Build in.

    I built this case around airflow and longevity rather than just looks. My 360mm AIO is mounted in an orientation that keeps air away from the pump, improving long-term reliability and reducing wear. The radiator uses a full push-pull setup for better airflow through the fins, lowering temperatures without needing higher fan speeds. Reverse-blade fans keep every intake looking clean while maintaining proper airflow direction. I also managed to fit two rear exhaust fans instead of the usual one, pulling hot air away from the CPU and VRMs more efficiently. The result is a cooler, quieter, and more reliable system. I love how much room the case has as well as the flexibility as far as mounting. The airflow is wonderful. The only con I could possibly mention of this case is the PSU being mounted behind the CPU, this means you must install your CPU cooler/backplate prior to your PSU.

    Plenty of breathing room.

    I simply adore this case. It looks great in feature photos and it performs well once setup. I recommend this for those who want to show off elite computers and take seriously the cosmetic look of their PCs. There are plenty of places to hide cables and the cable covers they provide are convenient. It sits upright and if I am placing this in a dangerous place like a rack that's unstable and wobbly, the feet on this case keeps it from tipping over because they are wide. I can sit this case on two poles on my rack and it will not budge and I don't worry about it falling on top of me. I feel great to know that I bought this case and plan to get a 2nd one.
