I Added a Graphics Card to a Mini PC – Here’s What Happened

In this video, I find out whether adding a GPU to a mini PC can make it run AAA games without building or buying a whole new PC. I upgrade the mini PC and try various ways to connect an eGPU using an M.2 to PCIe x16 riser adapter and OCuLink. Can this mini PC actually run games? Let's find out!

Modifying computer hardware, 3D printing custom enclosures, and using external GPU adapters (such as M.2 to PCIe or OCuLink) carries inherent risks, including potential hardware damage or voiding manufacturer warranties. Proceed with your own modifications at your own risk. Description: In this video, we transform a Dell OptiPlex Micro 7020 into a high-performance gaming PC by connecting an external desktop graphics card using both an M.2 to PCIe x16 riser adapter and an OCuLink eGPU setup. We cover the entire DIY eGPU creation project—from evaluating the stock mini PC specs to designing, 3D printing, and assembling a custom eGPU enclosure. After verifying hardware stability and BIOS thermal tweaks, we test the complete build across demanding modern AAA titles like Cyberpunk 2077, God of War Ragnarok, and Battlefield. If you want to know how to connect a dedicated GPU to an ultra-small-form-factor PC or turn a compact office workstation into a capable eGPU gaming rig without buying a whole new computer, this complete step-by-step build guide and benchmark test has you covered.
