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.

★★★★★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 Amazon cart. Validate that someone has built successfully with those parts first.

★★★★★Excellent ITX case, thermals better than expected, this is an amazing ITX case.
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.

★★★★★Great choice for me!
I really like this case. Built in it with a 3070ti, coolermaster 240 atmos, and asus b650e-i and i'm pretty happy with it. There were some challenges relating to the cooler and the corsair sf850 psu- the hose routing had a tendency to lay against the power switch and bumping my table could cause a power flicker. I had to get creative with some zip ties to hold the tubes well away from the switch but that has been the only real challenge with the build. *Maybe* the rear io cutouts are a bit tight, seems like i could do with another 1-2mm of clearance around my gpu connections. Looks great on the table and thermals are pretty good for a system this size.

★★★★★Missing parts, still great
TL;DR I really like it. It's small, and still has more space than I thought. Easy to build in, even as a first-timer. Very much recommend it. The one I received was missing the PCIe riser cable and the power switch cable, but that may have been a reseller issue, not a manufacturing one. Components I Used: AMD Ryzen 7 7700 CPU ROG Strix B650Ei Gaming Wi-Fi Motherboard Ripjaws S5 DDR5-6000 32GB RAM (x2) WD_Black SN770 1TB NVMe SSD Drives (x2) ASUS Dual Radeon RX 6600 GPU Corsair H100i Hydro-Cooling Fan Corsair SF750 Power Supply Cooler Master PCIe 4.0 x16 riser cable* The Positives I love the design and model. It's even smaller than I expected, but it still holds a lot more space. For a case that's the size of a shoebox, the internal layout makes it easy to work with if you have the right parts. I still have room left over to add SATA SSD drives, or maybe even drop in a small figurine for fun. The ventilation is exceptional. There are vents on almost every side, and the panels are easy to pop off when needed, which helps with airflow and access. I have decent cooling components, and since this is a development machine and not a gaming rig, the system has stayed cool to the touch since I started using it. The case is very straightforward to work with. This was my first PC build, and the process went smoothly. I’d recommend this to anyone who wants a clean, sleek, utilitarian setup. The Negatives My unit was missing several components that were supposed to be included. There was no screw bag, and some of the screws for the top and bottom inner panels were missing. Most importantly, the PCIe riser cable wasn’t included, even though it’s shown in both the manual and the product listing. I had to buy a replacement for $40, though I did receive a partial refund. The power switch cable for the case's power button was also missing. Only a reset switch cable was included, so I had to short the power pins on the motherboard with a screwdriver to turn the system on. That's pretty bad. I eventually repurposed the reset switch cable to act as the power switch. It works, but that’s clearly a hack and not how it was intended to be used.
