Review: 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.

## Questions & Answers

**Q: Does this include pci4.0 riser card cable ?**
A: Yes it has the cable.

**Q: What support is there for air coolers?**
A: I would be extremely surprised to find a air cooler that would fit into this computer. It was tight even with the pump alone that I used. I would stick to AIO water cooling.

**Q: Can this fit a 3080 evga hybrid?**
A: Likely yes. But it will use the radiator space so your cpu will have to be air cooled.

**Q: Can this case fit an sfxl psu?**
A: It technically will fit though it will make cable routing and management basically impossible. You can try an sfxl unit but just be ready to spend some with the cables and pushing them all in the case.

### ⭐⭐⭐⭐⭐ 11-Liter SFF Hall of Famer
*by J***H on 2 April 2023*

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.
