Don't discount what Maineah said. It can dangerous and deadly, and needs to be thought through. Removing the panels on the generator will reduce the amount of noise reduction; that is the main reason for the panels. I cut the bottom of my box out, welded a steel frame lowering the generator in the box, and the box is in open air in the bottom. I didn't have the electric cord you are referring to. Fan cooling, ventilation, and exhaust rerouting are the key. It is doable but you don't want to just squeeze the generator in there and run it.
