Perfect ITX case
I cannot tell how good The case is. Looks premium and can fit large 3080ti perfectly. I have build it with low profile air cooler as I didn’t want to use AIO. The temps are really good and u am having no issues at all. Most importantly you can fit it in a backpack. Portability is awesome.

11-Liter SFF Hall of Famer
This case is absolutely amazing, punching well above its weight class. Let's start off with what I have inside mine -- an i7 12700K and am RTX 3090 TUF, powered by a Cooler Master V850 SFX PSU. Man, does this case make it happen. The H2O is able to handle this kind of power because the CPU is liquid-cooled, and the GPU sits on the other side of this sandwich style case. The case itself is rock solid, utilizing a near tool-less snap-together design and plenty of ventilation for its size. It is larger than the previous model (Dan A4 SFX), due to the intention of this being water-cooled. I opted for an MSI CoreLiquid 240R ARGB V2, since the water block is small and offers ARGB. It tames the temps well on my 12700K. You'll need to make sure your AIO will fit in this case, as there are many that won't -- either because the pump/water block is too tall or because the hoses are too thick. You'll also want something that has hoses on swivel elbows. Otherwise, routing the hoses and closing this case will be next to impossible. This was hands-down the hardest aspect of building in this case -- managing the AIO hoses. The A4-H2O gets a lot right. You can cool some higher end CPUs, use a full length GPU, and a semi-pleasant building experience. To top it off, it looks amazing, and the parts are high quality. Just keep your hands off the case, as the finish shows off fingerprints well. This case is an excellent competitor for the NR200, because it's 8 liters smaller, and has nearly all-metal construction. To me this one is the obvious choice. Also in this form factor I would avoid i9 CPUs entirely. They eat up too much power, and make too much heat. My experience with this case has been fantastic, but it did leave me wanting more. Having a liquid-cooled, 11.24-liter PC means it's going to be a tad heavy. It's also too big to fit into my DSLR camera bag. I also think this case's width dimension would be a tight fit in a carry on-size tough case like one from Pelican. If you need a small form factor PC for saving desk space, this is an excellent option. That's the niche this serves for me, and it delivers. Maybe you can make this a portable powerhouse for more than gaming. Its too big and heavy for me. Personally, I've found my 8.1-liter KXRORS S300 case to be a better road warrior, because it fits in my DSLR bag and weighs less. Sure, that one can't be as powerful, but it games very well, albeit a little louder.

La caja perfecta, ojo con el proveedor. Amazon excepcional como siempre
La cajita una pasada, un poco cara pero se paga el premium de marca y tamaño. La tuve que devolver porque la caja necesita estar ubicada en un espacio abierto (normal, nada especial) y en mi caso particular la quería para tener un ordenador potente pero pequeño en la tele del comedor, ubicada en un espacio cerrado, con lo cual la ventilación era nula y los componentes se me calentaban al ponerme a jugar a pesar de la refrigeración líquida. La tuve que devolver la caja para comprar otra con entrada de aire/ventiladores en el frontal tras 2 semanas probando mil cosas porque no había manera de contener las temperaturas y desgraciadamente el embalaje original fue tirado por error ya que siempre me guardo todo religiosamente durante 1 mes. El vendedor (tercero) me abonó poco más de la mitad del importe sólo por esto a pesar de devolver el producto de manera impoluta, pero Amazon, como siempre, arregló la situación tras reclamar. Así da gusto.

Wonderful Case
The parts are mostly high quality and it fits a wide selection of parts in a satisfyingly snug way. My only gripes are that I had to get the flex cable replaced as it had intermittent contact issues, and the clips holding the ball studs of the side panels, which I had to print some alternatives for to tighten the fit. Otherwise the panels would rattle when moved.

Tiene unos hacks
Honestamente estaba aferrado a algo como el fractal design ridge pero como no llega a México me decidí por este y honesta mente es muy bueno considerando que puedes meterle más de 1 ssd no lo dice oficialmente pero donde montas una ssd puedes puedes poner una bahía de 2 y así tienes 1 ssd mas también donde está el orificio para hacer espacio a la grafica puedes insertarlas maximo 2 con presión de nuevo nada de esto es oficial pero es otra manera de hacer todo el espacio eficiente y en se tener más almacenamiento, espero les haya servido (no es mío oficialmente es de un yutubero ingles)

Harika ama kibar.
Hema Bilişim'e hızlı ve sorunsuz gönderim için teşekkür ederim. Kasayı TV yanına Konsol kullanım amaçlı aldım. Boyut ve işlevsellik olarak bence yeterli. DeepCool LE500 Marrs sıvı soğutma ile kullanıyorum. Biraz kibar duruyor taşımaya pek gelecek gibi değil. Tavsiye edilir.
