Can anyone please tell me for 5 or 10 of the units would a powered usb hub be ok to power them and what specs would it
Depends on how hard you want to run them. At its slowest (presuming it is the slowest), it'll work off of a standard 500mA port. Fastest I've run it (16.5Gh/s), it needed just shy of 1.3A. 10 units at 1.3A and you're looking at a 15A-20A hub.. not exactly something you'll find at your local Currys.Unless you want to put something together yourself / wait for sidehack's hub work, I've seen some recommendations for the Dipo 19-port 20A hubs. iirc they do have individual limiting fuses so you might have to split the load across more than one port.. somebody who's used/has one can probably clarify, or ask the user 'klintay', he used to sell them over on eyeboot.com
He's still selling a 10-port, 2A/port, 10A total one; http://www.eyeboot.com/10-port-usb-hub
heh no need to overclock them....according to www.tradeblock.com at current 288 usd btc price I will make (wait for it) $5.00 usd for the YEAR (yeah baby $5 bill baby)
if I use ONE of my TWO sticks at 8gb and it cost me nothing and the unit had free electric with 0% pool fee to boot
whoo who....

so the need to OVERCLOCK THEM is probably moot ...just saying
