Putting mine together the last few days (when the baby is alseep)
I somehow lost track of which way was forward on the fans (I relocated the two that come with the case to the front grill and have three others for the other spots 1-120, 2-80s) Do you happen to know if the open side is the direction air comes out of when it spins?
EDIT: Got a pic from the manufacturer's website which shows direction. I think...

Oh well, when it is on it will be obvious, I'll just have to pull my HD if I am wrong to switch it is all.
