I have a computer in a drawer here by my chair. I used a piece of 4" PVC vertical blind material attached to the drawer and to the back of the cabinet. That will form a smooth loop when the drawer is closed. I have all my cables attached to that strip. I didn't invent that. IBM did it on equipment where they had a bunch of cables going across a hinge or a moveable cover. It spreads the bending out evenly, secures the cables and keeps things organized out of other moving parts. You could do that here.
