I second that. As long as there's no LED fans, you don't HAVE to connect hdd / power LED's just because they're there. Simple solution.
If you dont even want the cables to tuck away, just pull the case LED's out of their mounts. It's not difficult. I've always changed the hdd/power LED's on all my personal cases. (I hate blue)
