I watched all the videos never heard that! Post the video here please. I would like to see that. Any laptop off the shelf short of a barebones notebook with minimum of ram could run one of these. Most machines made in the last 5 years have a minimum of 16 gig or ram. That is enough. No special graphics card is needed.
USB right to the control box is all you need.
Desktop or laptop is fine to use no special equipment at all. Please post the link to that video here so we can review it.
