Thanks, I appreciate the reply.
I see in the manual they mention a spot for a fan also on the right side (as well the bottom) , not on the back. I could have sworn the non RGB manual shows 1 fan in the front and the other in the rear. Can’t see why it would be different.
not sure how much good the fan on the tight side would do unless the hard drives really ran hot, so I think I’ll do the 2 top fan as exhaust as you suggest. Would you recommend leaving the glass top off or will the fans really be able to exhaust around it?
