Removed all but 2 of my fans. Think I'll get rid of one of the Power Supplies next and follow melmo's lead and remove all fans and have a larger fan pointing at the stacks.
How well does that configuration work with the single fan on top of each stack? If you lift up the top 4 units and touch the bottom one, is it cool to the touch?
Stacking like this really saves a lot of space... I think I have room for 10 more, but I'm not sure if I have the cash for them
