I make a habit of looping my excess cord up and wire tying into a neat bundle - but this discussion has me wondering... would coils of electric cable create some kind of electrical field that could pass along noise to patch cables. - (Isn't this kind of how a motor works? winding wire around and around?) It would seem to make sense that if you didn't have coils, or used a shielded cable you could eliminate that interference. But what do I know.. I only lasted 3 semesters as an EE student.
