Waiting on 4 Sticks. Will this work to power them?
http://amzn.to/1JYN9m2 10 Front facing Standard A USB ports
0.5 - 2A per port with 17mm port spacing
Upstream port support high speed (480M)
Box includes 1 x USB hub, 1 x 12V 5A Power Adapter, 1 x USB cable
Yeah, it would work quite well, actually. 17mm is plenty of room and even if you had a 10W fan you'd have 12W per stick which should let you hit 400MHz.
If you don't want to use a fan I recommend clocking nearer to 150MHz.
