Remorce Hahaha I had the same dilemma! Just about 5 min ago I took the stock back fan out, moved it to my 3 empty 5.25" drive bays, zip-tied it to the pop out cover things (they already have filters! Hooray!) and voila! My hyper212+ push pull config shoves air out the back grill with or without that fan in the way so I figured why not! It now lines up perfectly with the pull fan of the Hyper212+ and is feeding it nice fresh cold air. My temps are now at 26c idle on a 4.8ghz i5-2500k from a previous 30-32c idle.
