When you see this system on your desk, you will think what a cute little PC... Minesweeper will certainly run without lags.

...until you take a closer look at the configuration and realize that it probably has the most powerful gaming hardware installed. Okay, it's not a 4090 graphics card, but the high-performance 4080 SUPER from ZOTAC.

The biggest problem with ITX builds is... the size. Such powerful hardware gives off a lot of heat. Where to put it in ITX systems? That's where the DAN Lian-Li A4 H20 comes in handy. It offers space for a 240 radiator for water cooling.

It was a challenge to fit everything into the case, but the DAN case has a very specific concept to make it all happen. However, the case is so small that there is no standardized cable concept. - You have to be careful that no cables get tangled up in the water cooling system. - You should be careful which water cooling system you use. I only found what I was looking for on the third water cooling system. I first wanted to use one from Arctic, but the cooler doesn't fit on the small motherboard. My second choice was one from Enermax, but the cooler and active fan were too high for the case. I ended up with one from Fractal Design, which fits in well. - You should make sure that you use a suitable graphics card so that the 12VHPWR power connector is not bent too much. - You should be careful that the ATX power cable does not press against the RAM. - You should also make sure that the rigid water cable does not press against the RAM.

That sounds a bit much, but with enough dexterity and patience you get a real "power cube" as a gaming system. The water cooling works very effectively and this also keeps the noise level low.

It was a lot of fun to put it together.

All in all, a sensational system. So little space and yet so much power. And even in benchmarks, heat is not an issue, even though it is an ITX system.
