What I do notice is that you can possibly, create a exhaust vent (with fan) out the side of your house. and contain the pcs in that area to blow heat out. Air through front of the pcs, hot air out the back into the vent outside the house.

In my case, I ran all the wires under the carpet to my closet, then wired up a fan off the top of the closet to blow all the hot air up into the attic, while the cool air was sucked from the gap under the door. This improved the temperature of my room incredibly and the computers are as cool if not better then all the heat trapped in the room.
