Folding cables serves two purposes; to create a super clean looking system and maximize air flow going though the computer case. Nothing messes up air flow more than a bunch of dangling IDE cables. Rounded cable helps this problem but they still tangle inside the case and still block airflow. A properly fold IDE cable will snake along the sides of the case so air flow is not disrupted and will look cleaner than anything you can do with rounded cables. - The Tech Zone
