I have a desktop PC and need to connect an additional graphics card (PCIe Gen 5 interface) to it, but there is no room inside the desktop PC for this additional graphics card. I heard there is a type of device called external GPU dock. Can you please give a solution (what things I need to buy) to connect the graphics card externally? PS, The desktop PC is running Ubuntu. Please make sure the solution works from hardware installation to driver installation on Ubuntu. Thanks.
