So due to limitations of my wallmount rack I found myself buying the 4u-4408 case to be able to fit 8 discs and my xeon-d board with gpu inthere. Now for some reason I thought that there would be enough airflow over the discs if I mounted the 4x 80mm in the front and 2x 80mm in the back. But im beginning to have my doubts. Im considering replacing the 4x 80mm in the front, with 2x 140mm "just standing up" in the middle of the case - a homebrew fanwall if you will.. Anyone worked with the case and have any experience to share?
