Lian Li A4-H2O Mini-ITX PC Case, Triple-Slot Mount GPU, Aluminum Exterior & SPCC Steel Interior, 240mm AIO, SFX Sandwich Layout, PCIe 4.0, Supports SFX/SFX-L PSU (A4-H2O A4 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.

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.

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.

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.

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.

I recently built a newer system and was surprised how tiny this case is and how easy to build around.

Also, get a board with USB C front panel connection if you plan on using the front panel USB C socket. Other than that, I'm loving this case. This could actually fit some 4000 series cards as long as they are 3 slots max and 322mm long. =)

I spent the last week with multiple cases and builds to make the perfect ITX with 240mm AIO. I had to return the other cases as they were a thermal nightmare, not compatible with measurements, riser cable failure and was way too loud air cooled. Lian Li hit the mark with this category of case. This was a fun build for someone who had one of their cases way back in the day remembered their quality bar. Build took 45 minutes and everything fit with a little fun cable management. SFX power supply, 4070 super with the riser set to the case panel, AMD 5900x, two m2s and a cooler master 240mm kit. I ended up with two ASUS Rog 120mm fans and they are super quiet with temps around 42C CPU and 55-60C GPU for games. Idling around 34-35C and 36C GPU for youtube or basic aps. I've been building systems for a long time and this was a great adventure making the lunchbox form factor. *Pro tip, leave the plastic on your components until you are finalized with fitment and then remove to prevent scratching during install.

The material and build of the case are very good. A nice option for Mini-ITX builds. The unit I got had defective HD audio front panel connector, headphone jack and microphone jack did not work with two different motherboards.

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.

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.

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.

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)
