Well the holes are bigger and are more numerous on the back, therefore the back is the only part i taped up (used decals so it would look cooler). I left the front holes un-taped for a little airflow, but i also use mike's heatsink which mostly covers the holes up anyway.
Both ends it is then. I am only going to be running on the black top but would rather be safe than sorry. I am waiting on mike to finish up the end covers! Thanks guys.
