In this video I’m building what I’d genuinely call a dream ITX gaming PC inside the NZXT H2 Flow, and the whole point is simple: small footprint, big performance, and none of the usual ITX headaches if you plan it properly. I walk you through why this case works so well for an ITX build that still wants proper airflow and a chunky AIO, then I get into the stuff that actually catches people out—like GPU sizing and the little quirks with the H2’s fan setup. For the core parts, I’m pairing a Ryzen 9850X3D with either an RX 9070 XT or an RTX 5070 depending on what you can get for the right money, and I’m cooling it with an NZXT Kraken Elite 280. I also cover the practical side of building in a compact chassis: cable routing, clearances, and how to avoid turning your “clean ITX build” into a hot, noisy mess. If you want an ITX gaming PC that looks premium, runs cool, and still delivers serious FPS per pound, this is the blueprint.
