- GGiuseppeVerified ReviewerReviewingH9 Flow RGB+I recommend this productRated 5 out of 5 stars3 months agoMolto molto soddisfatto 😁
Ho acquistato questo case per sostituire il cade del mio pc , io ho acquistato un pc nuovo con tutti i componenti usciti nel 2025 quindi fascia alta 9800x3d 5070Ti mobo x870 gaming plus wifi ecc ecc ho acquistato questo case insieme all’alimentatore nzxt c1200 perché volevo migliorare sia l’aspetto sia il raffreddamento e l’alimentazione per futuri upgrade dato che avevo un 850w comunque è stato facilissimo assemblare il tutto è stato il mio primo pc assemblato da me non lo avevo mai fatto è stato bellissimo e divertente a volte spaventato quando dovevo toccare la cpu ma per il resto è stato molto molto facile il case è pieno di spazio dove passare i fili quindi ti permette di montare tutto con estrema accuratezza anche ai dettagli i materiali sembrano davvero di ottima fattura ma sopratutto sono passato da un case ( itek) dove io giocando a Warzone facevo 80/83 gradi di cpu a questo che adesso dopo vari giorni di prova e gioco non ho mai superato i 64 gradi in game mai veramente molto entusiasta del prodotto sono rimasto a bocca aperta ora vorrei solo prendere il kraken élite 420m nero però non lo trovo da nessuna parte spero sia al più presto disponibile, comunque su questo sito da cellulare non si riesce a mettere i prodotti nel carrello piccola segnalazione magari potreste sistemarlo un po’.. che dire davvero molto soddisfatto grazie NZXT complimenti per il prodotto e vi prego fate uscire il kraken élite rgb nero da 420m 😭😂 ps il dissipatore che ho al momento è quello…

This case is a charm to work in. Every form factor works in this case. Tons of room and everything was really well thought out.
- JGJoshua G.Verified BuyerReviewingH9 Flow RGB+I recommend this productRated 5 out of 5 stars3 months agoExcellent quality. Need slightly taller cable channels.
Excellent case. Third NZXT case I’ve owned and super happy with it. Only negative is the upper channels for the CPU cables need to be a little taller for back-connect motherboards. Like 2-5mm taller. The connector latch couldn’t squeeze through to fully seat the cable into the motherboard. Won’t take a star off because I love this case still.

- CChristopherVerified ReviewerReviewingH9 Flow RGB+I recommend this productRated 5 out of 5 stars4 months agoQuality case. Great CPU and GPU temps.
I've had this case for a few months now. Overall, i'm very happy with it.
Great build quality & excellent aesthetics. It has very good temps for this style of case. It also has lots of room for your components and airflow.
You can do push, pull on the side. I tried it. It works/fits. But, only with 120mm fan/radiator set up. Only standard width radiators will fit. The length of the graphics card dependent. It was a tight fit with my current set up(a mm gap from my anti-sag bracket).
Ultimately, I decided to go push pull on top with 420mm Kraken fan/radiator set up. Overall, I'm very happy with the case. This is my second Nzxt case & overall both seem to be quality pieces.

Es ist absolut das beste Gehäuse auf dem Markt für einen fairen Preis. Das Dual Chamber bietet sehr viel Platz und einfaches legen der Kabel. Das Gehäuse bietet eine schöne Optik für das Build und somit auch viel Platz für Lüfter, AiO Kühlungen und Grafikkarten. Der einzige Nachteil ist, dass man bei meiner MSI RTX 5080 die GPU Halterung nicht nutzen kann, da die zu kurz ist oder eben zu viel Luft zum Boden ist. Daher musste eine andere günstige Alternative her.

- NNickReviewingH9 Flow RGB+I recommend this productProduct Standouts Great Quality, Performance, Ease of useRated 4 out of 5 stars4 months agoSo close to being great. Still the best case I’ve had.
I’ve had 3-4 cases in the past. The lian li dynamic mini, Nzxt h9 flow 2024, Phantek evolv x2, and now this.
It’s a really good case and well diverse. Personally, I think a bunch of 360mm fans doesn’t look as good as 420mm fans that fill in all of the space. 420mm (140x3) fans provide a slight temperature decrease by 3-4c under load but the main advantage is the less noise they produce. Saying that, 360mm fans will work fine and the temperature difference doesn’t really matter. But, if you want the best performance and aesthetic then get 420mm. The side mounted radiator also looks better than a top imo. A top mounted radiator eats up a lot of vertical space. The side mounted 420mm radiator fills in the angled space. Also, the view of the fans aren’t cut off as they would be with a top mounted. I used this case with a backward connect motherboard which had some issues.
Performance wise, it’s what you would expect you get in a case with a bunch of 140mm fans. The best performing case I’ve had.
There’s only one dust filter and it’s on the bottom. I don’t know why they didn’t add dust filters on every other meshed area of the case because there’s a lot of them. The holes are small enough where I don’t think too much dust will get in but definitely not as small as the cut outs of a dust filter.
The case is almost tool-less. NZXT really thought it through. You dont even need to watch a YouTube video or read the manual, it’s pretty straightforward. Most of the screws are twist…
- CMchris m.Verified BuyerReviewingH9 Flow RGB+Product Standouts DesignRated 3 out of 5 stars5 months agoits a good case however
It is a good case however there is still much that needs improved. There is a lot of room for activities.
To mount water-cooling on the front side is kind of a pain and you cant put the radiator in the correct orientation due to there not being enough room for the lines. You also cant do push pull in this location. Overall im jus meh with the case. I havnt tried to top mount the Rad yet that will be a whole different endeavor.
The case is also not tooless. There are way to many tiny screws. Way to many.

I have already built a setup in a H6 Flow RGB, but for myself it would have been too small. Previous H9 would have been an option, but I do not like the arrengement of the side fans in the plane of the mainboard. Then I have seen this in the Computex 2025 news, and fell in love at first sight. Just what I've been looking for.
+ Price is somewhat horrendous, but hey, it comes with all the fans + the controller we need, and in the end, it looks marvelous.
+ Quality is the usual nzxt level, keep up the good work guys.
+ Air flow is just supreme, noise level can be kept down at low temperature (and I somehow love the turbine noise at startup when all the fans are released at 100% xD ).
+ Installation, hardware upgrade is a walk in the park, it's the most spacious case I ever worked with.
+ It looks awesome!
Still some minor points for improvement:
- Rear fan placement and implementation needs a second thought or two, it stands out in the wrong way - not as fluid and smooth in design as all the others.
- No in-house solution for GPU anti sag. Still had to find a 3rd party solution and that does not look so good. The nzxt vertical bracket would also look strange in this one, and not everyone wants a vertical GPU that hides most of the mainboard.
- Cable management (cable holes) between the two compartment could be somewhat better covered.
Due to pricing and the few little annoyances I would rate it 9,5/10, but no question about the 5 stars rating. Would buy it again. And…

Good case, good airflow. Everything is perfect inside the case
