I would say no for several reasons. one, when it comes to wiring up your machine, they don't give the job to one guy if you select 'yes' or a different guy if you select 'no'. its the same dude thats gonna wire it regardless in most likely the exact same fashion.
second, most cases nowadays are designed with wires going through specific cutouts. so its hard to make it "messy".
i did not select it and everything came nicely bound and correct. couldnt imagine it any better.
i did get the packing material. figured it was like $20 insurance. didnt want to have something come loose or whatever and have to send it all back and wait.... not worth $20 so i just paid it...
