Hi all!

I'm trying to build a noise reduction enclosure for housing 4 units of D3 and 1 unit of S9. I want to go with a push/pull format for the enclosure using 5 x 120mm case fans for each side. Since there's no motherboard, how do I power these case fans? Can I use some kind of USB adapter to power the fans?  I can't control the fan speed either but that's another problem for another day. Any feedback would be much appreciated!!
