Switch – Cable management strategy for a small chassis switch

I'm working with a small site buildout that contains a single HP ProCurve 4200vl chassis switch. The data cabling contractor did not provision for any cable management. I'm looking at the rack pictured below and would like some suggestions on how to cleanly patch down to the switch below without vertical managers. I wanted to avoid full vertical management since this setup will only utilize 40-50 cables. Is there a clean way to do this? Would something like the NeatPatch be the best approach? If the answer is velcro, I guess that works, too…
