I have thought about cutting up a Raptor Grill to mount LEDs into...and I did go as far as Photoshopping a few different design ideas with various lights.
What stopped me was the $500+ it would cost for a new plastic grill, I wasn't about to chop up the only one I have. I would love for someone else to do it though!
The $500 "screw up fee" is a bit steep isn't it? I don't quite trust myself enough with a dremel.
