hi have an office with server room i was thinking of putting it in so noise is no problem, and setup looks easy enough

could elaborate more
 a) why aren't they for a new person?
 b) are they reliable
 c) the is the calculation thing correct?

hi i'm really new to this and have read lots and seen quite a few videos
i have been thinking about buying a Spondoolies-Tech SP30 Yukon are these any good??

and as i've never done this before are the calculators correct at 4.5th/s i would see a return of about 0.06 bitcoins per day
