Review: 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.
Review: Perfect Case - It's the perfect case for my needs: - Small even for SFF standards. - Quality materials. - Decent cooling options given the space you have. - Fits a pretty big GPU. - Supports air cooling if you pick the right size. Extra Notes: - I'm undervolting my 7700X and the fans are inaudible during day to day use, but do get a high quality fan if you go with air cooling. - Cable management is the trickiest part, as others have said. It's best if you pick a PSU that is known to work well with the stock cables it comes with or get custom cables. - It was easier to build in than my last mATX case, simply because you are more limited to parts and compatibility, but you must do research to build in this case. Do not just throw seemingly compatible parts in your desertcart cart. Validate that someone has built successfully with those parts first.

## 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.

### ⭐⭐⭐⭐⭐ Excellent ITX case, thermals better than expected, this is an amazing ITX case.
*by C***G on May 25, 2023*

This is now the best case I have ever owned. Super small, quiet, aesthetically pleasing, well built. Thermals (and noise - Noctua fans...) are better than you would expect with such a cramped case. This case is also surprisingly quiet. Get custom cables if you can, this will aid with cable management. Modular PSU's are a must with this case, non modular PSU's will not work as there is not enough room for spare cables. This case replaces my excellent Corsair 250D that is large for a ITX case but has excellent thermals. This machine is used for gaming on a 2K monitor. Easy to build as all of the panels are removable. CPU: Intel Core i5 13600K (not overclocked) never gets above 55-62C (better cable management or custom cables would probably improve this to drop below 60C) CPU Cooler: NZXT Kraken X52 (long hoses but they fit fine) with 2 Noctua 120mm x 25MM fans pushing out and 1 120mmx15mm slim Noctua fan on the bottom pulling air in. This fan is not mounted as there is not a mount in this spot however, it works fine and does not move at all. GPU: RTX 4070FE - (not overclocked) Stays at 70C or below. Very quiet. PSU: 850watt Cooler Master fully modular SFF 2 M.2 drives, no 2.5 SSD, don't need them anymore.
