Style: A4-H2O ITX Black
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.

The main gimmick of this case is the ability to mount psu at different heights depending on your needs, if you want watercooling you'll need to place it lower for more room at top, want a long gpu place it higher to increase clearance upto over 400mm, want both you'll need a sfx psu which is easier to cable manage anyway, want a thick gpu, upto 4 slots but anything thicker than 2 you won't be able to have bottom fans or drives Pros. Compatible with fullsize components Looks nice(imo) Easy front panel connector Relatively compact Outstanding build quality Affordable Cons. Horrible cable management options Screws come mixed in bag Limited compatibility(may not match the maximum listed dimensions) Parts used in my build GPU: 7900gre hellhound PSU: Toughpower gf3 1000w CPU: ryzen 7 7800x3d Motherboard: mag b650m mortar wifi Cpu cooler: deepcool assasin IV(may be unavailable due to recent ban, I bought it a while before I learned of the Russia issue) Fans: artic 120mm 5 pack, I could only fit 3 with my gpu blocking the bottom 2 Would definetly reccomend to experienced builders or anyone willing to do the research on each components compatibility(or want to take the gamble) Edit: it's also important to mention that come cpu coolers like mine will prevent you from installing the side fan bar, whcih means even tho there is room between my cpu cooler and psu for a fan I can't put one there since the part the fan attaches to is blocked, because of that I could only fit 3 fans, 2 on the top and 1 in back, all exhaust unfortunately whcih means it's a negative pressure system, air can get in through the sides but this will lead to some dust build up

Style: A4-H2O ITX Silver
Love this little case. I watched the Optimum Tech video where he found a way to watercool a CPU and GPU in this tiny ITX case and decided to replicate it. I was able to cram a 240 radiator, a XPSC 240 radiator on the side, a 4090, and a i7 14th gen, with Modultra pump/waterblock. This thing is a solid brick but my temps never get above 10c over ambient, and I can pack it in a carryon suitcase to take with me when I travel. The inlcuded instructions are easy to understand, but there's not much to this case either. And lets be honest, if you're building a SFF PC, you've likely not new to PC building. If you are a newbie, do yourself a favor and get an ATX case. This is not a case for beginners, and I wouldn't recommend this case to most people I know for that reason. However, this is one of the smallest form factors you can get that supports a 240mm radiator. While you don't have to go crazy and cram 2 radiators in it, you can fit an AIO in no problems.
