Introduction

The Asus ROG G20CB is a compact gaming desktop that uses custom cooling and a specialized case layout. Replacing the graphics card (GPU) can significantly boost performance, but due to the small form factor and custom internal design, it's slightly trickier than on a regular tower. This guide will walk you through the process carefully.

Check GPU size: The G20CB supports small dual-slot GPUs (generally under 10.5 inches / 266mm long). Only 6-pin or 8-pin PCIe connectors.
