good case
The sandwich-style CPU case is an excellent choice for its price. Notably, this design facilitates efficient heat dissipation from both the GPU and CPU in both case faces. However, it doesn’t offer ample space for large coolers or high-energy-consuming CPUs. The product arrived promptly. Keep in mind that pairing an AMD 7700X chip with a Noctua NH-D15 might fall a little short in cooling performance.”

First time build, worked pretty well
It fit all the parts that I wanted to put in there, and looks beautiful. Had it for 2 months now and have really enjoyed it. There is barely any clearance between the fan shields I placed and the riser cable (they pretty much touching), but I haven't experienced any issues with that yet so it doesn't seem to be a problem.

Very convenient ITX case
-CASE: KXRORS S400 (13.4 x 10 x 8", 10.8L) -CPU: i9 9900k (stock voltage) -COOLER: Thermalright AXP120-X67 -RAM: 32gb (2x16) DDR4 HyperX Fury 3200 -GPU: MSI GTX 1080ti -MOBO: ROG STRIX z370-i Gaming -M.2: 2x NVMe SSDs -SSD: 3x 2.5" SSDs -PSU: Lian li SP 750W 80+ Gold -CASE FANS: 2x Thermalright C12015 Overall, I'm very happy very this case. Bought for practicality rather than aesthetics as I travel a lot and this delivers much better price to performance than a laptop. Chose the S400 over the S300 because the extra 10mm of CPU cooler height provides much better cooling options and provides extra space for the 2.5" drives. For me it was definitely the right choice. Notes: -Good temps (idle around 42c, no thermal throttling when boosted. Running mobo in performance mode but CPU is not overclocked. Approx 12000pts on Cinebench R23. -Technically the max cooler height is supposed to be limited to 65mm, but I used a 67mm and it fits (though it is snug). Runs very quiet with no turbulence, I think the rubber pads on the Thermalright AXP120x67 really help. -There's supposed to be space for a 90mm fan below the PSU but in practical terms it's impossible, don't bother. The PSU cables get in the way and I don't even think it's necessary. I put a 2.5" SSD there instead. -I also mounted 2x 2.56" SSDs behind the GPU (had to remove GPU backplate) -I attached small stereo speakers to the top of the case internally, useful just for listening to podcasts etc. -I removed the top handle of the case so that it fits easier into a backpack. -For anyone using the ROG STRIX z370-i Gaming motherboard, its limited to 95 watts by default. (Perhaps this is standard practice for ITX mobos) But I recommend going into the bios and switch to performance mode.

Stuff It...
Yes, yes that is a Merc 6800XT stuffed in there... The case said 335mm, the card said 342mm and ready or not here I come!!! lol... But seriously I did have to Dremel just a bit... So the case also said ok, 65mm cpu height max... The CPU cooler said 67mm and you better make room... So the case did, "had to Dremel a little bit more... And now, BOOM!!! Masterpiece... I've deemed her the Lunch Box... 💛🖤🤍... Yeah yeah I know, eat your heart out...

Great little lunchbox sized ITX gaming chassis
So the case is extremely well made for the price, and it is pretty easy to build in. This case moonlights under a lot of names so finding information is a little challenging but other than that it's a 5 star buy. My only real complaint is the pcie 3.0 riser, not that it really effects performance. If you're interested in what's inside my case: Gigabyte b760i aorus pro Intel i5 13600k (thermal wright contact frame used) Thermal wright axp120x67 Powercolor Hellhound 7900xtx Corsair sfx 750w platinum Samsung 980 2tb 32gb Corsair vengeance 6000 cl30 This is a little gaming monster, used primarily for 4k gaming (high refresh esports stuff ) and atmosphere rich single player stuff (starfield, bg3 etc). Happy with the performance and the temps. The noise levels are minimal with some fan curves, and the front USB port and USB c ports are handy (though I removed both for better airflow for the GPU). Overall I'd highly recommend this case. If you want to get a pcie 4.0 riser I went with Linkup. The 20cm dual reverse riser is a little longer than needed and the 18cm is a little too short. 19cm is the size you want.

Just Great :)
Had a good time assembling this very compact build. Used my old CPU/GPU combo (9900K + RTX3080 ) in this build and couldn't be happeier. The case is perfect for air cooling due to its all mesh design for both CPU & GPU. The White coloured case looks stylish and fits the asthetics of my setup very well . Have also used an 850watt SFX PSU from FRACTAL.

Awesome itx case
Awesome itx case easy to build and has plenty of room for a large graphics card and nice and sturdy handle makes it easy to carry need to get low profile case fans for airflow! Still need to figure out cable management after installing case fans! But overall a great case!

Really nice case, but the riser cable just won't work (cust. support unreachable)
I love this case, and it fits my build almost exactly, but I finally got my GPU and it just doesn't work with the riser cable. It works fine when it's in the motherboard, but fails whenever the riser cable is connected. I'm disappointed Aug 21 2024: It's been ages and I still can't even get in contact with customer support, so I just can't recommend this.

My first ITX build and it went pretty smoothly with this case. It comes with a Gen 3 PCI-e riser, so be sure to configure that in your BIOS to set it to Gen 3 instead of Auto/Gen 4. You can only fit a a lot profile air cooler so pay attention to that as well. No regular size air coolers or liquid coolers. Installed a 120mm x 25mm case fan on the front part of the top panel. Wanted to do the same to the back part of the top panel but the clearance height is a lot smaller so you'll need to use a 120mm x 15mm case fan instead. Diagram says there's room for a case fan at the bottom as well but honestly I don't think that's possible as you'll need that space for the cables. But otherwise it's a great case that's smaller than the size of a shoebox. Top handle is nice but I don't think I'll be using that only when carrying the unit around - will put it into a bag or support the bottom.

Es un buen gabinete pero solo lo recomendaría para partes con un bajo TDP, ya que al ser de estilo "sándwich" y el pcie riser justo detrás de tu GPU, esto hace que el calor no se disipe lo suficiente por el contacto con el cable, por ello la recomendación de partes con un bajo TDP, incluso utilice 2 ventiladores para sacar el aire pero no ayudo demasiado. Lo utilice unos meses con un ryzen 5500 y una rx 6600 para juegos poco demandantes (por no decir viejos) y la GPU siempre estaba en temperaturas mayores a 70° y en el hotspot mayores a 90° en ocasiones, por lo que en uso prolongado puede afectar la vida útil de tus componentes, quizás dirán exagero por el tema de las temperaturas, pero con la alza de precios, especialmente de GPUs, conviene mantener las temperaturas lo más bajas posibles para alargar aún más la vida de tu tarjeta de video, especialmente si vives en un lugar donde la temperatura ambiente suele ser alta (como es mi caso). En cuanto a la calidad del gabinete, es muy buena, no se siente "frágil", al contrario para su tamaño y peso se siente bastante robusto, eso si, el espacio es bastante limitado, recomiendo utilizar una motherboard con al menos 2 puertos nvme si quieres la mayor cantidad de almacenamiento posible, para evitar usar mas cables con un SSD. No es malo, pero recomendaría otras opciones como el NR200, al cual migre mis componentes y las temperaturas tanto de CPU y GPU no pasan de 75°.

I bought the S300 and I didn't have issues fitting it all in, but I did find the lack of airflow making it all warmer than I felt comfortable. I decided I didn't like it, but I still wanted keep the look so I noticed this after realized it's only like 3cm taller and wider, but it made all the difference! This can have 2 fans on the top which is what they should've done with the S300 because it's all back to a nice 30-35 degrees which is what it should be when idle and I can feel the fans blowing the air out from top. If you're looking at the S300 and then just noticed this, definitely consider this one just because that slight extra space allows for better airflow! Something PC users that game a lot would benefit from!

Really nice build! No regret buying this instead of S300 as this model can accommodate 2 fans from top.
