If the kit is in a rack, I'd make sure it's got sides and a door and then
stick a fan tray in the top to draw the air from the bottom to the top,
then
you'll need a way to get rid of the excess hot air out of the top - some
racks can have chimneys to help with this.

Other thing to consider is what's the temperature of the air coming in -
the
higher that is the less cooling effect it provides
