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. 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 caja perfecta, ojo con el proveedor. Amazon excepcional como siempre
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.

Geniales Mini-ITX-Gehäuse – Edle Optik und durchdachter Einbau!
Wer auf der Suche nach einem kompakten, aber extrem leistungsstarken Small-Form-Factor-System (SFF) ist, kommt an diesem Gehäuse kaum vorbei. Das LIAN LI A4-H2O hat mich auf ganzer Linie überzeugt. Design & Optik: Das Zusammenspiel aus schwarzem SPCC-Stahl und gebürstetem Aluminium sieht absolut hochwertig und edel aus. Es ist minimalistisch, zeitlos und macht auf jedem Schreibtisch eine verdammt gute Figur. Die Verarbeitung ist, wie von Lian Li gewohnt, erstklassig. Einbau & Bestückung: Trotz des extrem geringen Volumens (ca. 11 Liter) lässt sich das Gehäuse super bestücken. Das clevere Drei-Kammer-Layout sorgt dafür, dass man die Komponenten logisch und ohne Frust unterbringt. Das Gehäuse lässt sich von fast allen Seiten öffnen (Paneele sind gesteckt), was den Zugang beim Schrauben massiv erleichtert. Der Einbau einer 240mm-All-in-One-Wasserkühlung (AIO) für die CPU geht reibungslos vonstatten. Dank des mitgelieferten PCIe 4.0 Riser-Kabels findet selbst eine große Triple-Slot-Grafikkarte problemlos auf der Rückseite Platz. Fazit: Außen kompakt und edel, innen ein echtes Raumwunder. Der Hardware-Einbau macht trotz des engen Raums richtig Spaß. Eine absolute Kaufempfehlung für jeden ITX-Enthusiasten!

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.
