Lys Three | RTX 5090 32GB + Ryzen 7 9800X3D | Ready-to-Go Gaming PC | PC36

✨ Lys Three

The pinnacle of white builds

Lys Three is a flagship, all-white showcase build: AMD Ryzen 9 9800X3D on an X870 platform paired with the mighty RTX 5090 (white), presented in the Lian Li O11 Vision Compact. This system is built for 4K ultra settings, insanely high refresh esports, and demanding creative workloads, all while maintaining a cohesive white aesthetic from case to cables. Balanced airflow, pristine cable presentation and top-tier component choices make this a true statement piece with performance to match.

🧬 Built to last, designed to evolve

This system is built on AMD's modern AM5 platform, which offers one of the best CPU upgrade paths available today. That means you can start with a great processor now and still have room to move up the stack later, while keeping the same motherboard, case, power supply and most of your core components. GPU, storage and cooling are all easily upgradable so the system can grow with your needs over time.
