Project violet | enthusiast watercooled gaming pc rtx 4090

Project Violet is a handcrafted, enthusiast-grade custom water-cooled gaming PC, designed and built by me, @fps_labs. This system combines top-tier performance with a fully custom liquid cooling loop, delivering exceptional thermals, near-silent operation, and a striking purple aesthetic.

Powered by the Ryzen 9 9900X3D and an ASUS ROG Strix RTX 4090 (custom water-cooled), it handles 4K gaming, competitive titles, and demanding workloads with ease. Every component has been carefully selected for both performance and visual harmony, making this build as much a showcase piece as it is a powerhouse.

Built inside the Lian Li O11 Mini V2 with premium components throughout, Project Violet is ideal for enthusiasts who want a high-end system without the complexity of building and tuning a custom loop themselves.

You’re welcome to come check it out in person and try it for yourself. If you’ve got any questions or want more details, just send me a message anytime.

I also have other computers depending on your needs or you can message me for any requests.
