the only thing in front is the ON/OFF switch and the DVD/Media Lab.
I have changed the whole design,
BEFORE it was air comes in through the front holes and is blown out the back. The problem with this is there are a bunch of wires, PS and brackets slowing down the air.
NOW air is blown accross the computer from the left side to the right. The PS and HDDs are Under the mobo so that frees u all the space (no bunch of wires or junk in the way to block air.)
