The QUASAR — Small Footprint, Flagship Power

The Bespoke Builds QUASAR pairs a 24-core Intel Core Ultra 9 285K with an NVIDIA GeForce RTX 5080 16GB — a balanced high-end combination with the GPU muscle to match the CPU — inside the Lian Li O11 Vision-M, a compact dual-chamber case with panoramic glass on three sides. The centerpiece is the cooling: a 360mm liquid cooler crowned with a 6.67-inch panoramic AMOLED screen that can show live CPU/GPU temps, custom art, or GIFs. Eleven RGB fans light the whole interior, and for the full command-center look you can add the Thermalright Trofeo Vision 9.16" — a 1920×480 widescreen display that snaps magnetically onto the top of the case and runs off a single USB-C cable.

Frequently Asked Questions

Is this PC good for 1440p gaming? Yes. At 1440p high settings the RTX 5080 averages roughly 110 FPS in Cyberpunk 2077 up to 380+ FPS in Valorant. See the table above for each game.

Can it handle 4K gaming? Yes. At 4K high settings it averages roughly 85 FPS in Cyberpunk 2077 up to 260+ FPS in Valorant, with DLSS 4 adding further headroom in supported games.

Why pair the RTX 5080 with the Core Ultra 9 285K? A 24-core flagship CPU is wasted behind a mid-range graphics card in demanding games. The RTX 5080 gives this build balanced, high-end performance at 1440p and 4K, so neither part holds the other back.

What is the optional top display? The Thermalright Trofeo Vision is a 9.16-inch 1920×480 IPS screen that attaches magnetically to the top of the case and connects with a single USB-C cable. It can show system temperatures, clock speeds, images, or video.

What does the cooler screen do? The 360mm liquid cooler has a 6.67-inch AMOLED screen on the pump that can display live CPU and GPU stats or your own images and GIFs.

How big is the case? The Lian Li O11 Vision-M is a compact dual-chamber Micro-ATX case — noticeably smaller than a standard mid-tower — with glass on the front, side, and top. It still fits full-length graphics cards.

Is it good for streaming and video editing? Yes. The Core Ultra 9 285K's 24 cores handle gaming and streaming or editing at the same time. If you edit large video projects, the 64GB RAM upgrade is recommended.

Does it come with Windows installed? Yes. Windows 11 Pro is installed and activated with drivers ready to go.

Can it run VR? Yes. The RTX 5080 comfortably exceeds the requirements of current PC VR headsets.
