I gotta agree with Sazar, definitely worth trying to do something with those wires.
Also, the airflow from the case fans is designed to work with the side on and will cool better with the side on. If you can get a side on it, it'll improve air flow. The other thing to bear in mind is if you have to many fans blowing out and not enough in you'll get low pressure in your case which won't cool your components as efficiently.
