Hey guys. Im putting together a new build here soon and im looking to get an Antec 920 liquid cooler for my CPU. It will be going into a Thermaltake Level 10 GT Snow, and i noticed there is a place for a 120mm fan at the bottom of the case facing down through the open grill/filter. My question is what way should i face the fans? Down and out of the case or up and into the case. Any insight you might have would be appreciated. Thanks
