where are you going with these questions?
You are using a 5v based board, and your fans are drawing from the 12v. There will be some cross voltage issues. At most, you would use about 30 or so, as that will give you roughly around 10A usage. You have to account for other things as well, like hard drives, cdroms, etc.
And exactly which BlueStorm are you referring to? I won't assume which model you are referring to.
