may be workable at 6 sticks a fan with 10 hubs you would be okay with 60 sticks. long term 24/7 365.
if you get that psu to run 75 sticks and a few fans longtime I would be impressed with the quality of it. 60 sticks = 150 watts 4 fans = 10 watts that is 160 watts out of a 200 watt psu. that is about the limit for long term use.
still 20 hubs = 170

http://www.amazon.com/gp/product/B000S7AQF4/ref=oh_details_o03_s00_i01?ie=UTF8&psc=1you would be at 250 usd for 120 sticks and 0 overload issues.
I forgot the fans so 300 usd for 120 sticks and no overloading. possible that you could do 7 sticks and a fan which would be 140 sticks and no overloading.
let us know how it holds up with more sticks per hub and per psu.
