Newly Discovered Bitcoin Mining

Hello I Just Recently discovered bit coin minning i own a cyber cafe and am looking to use the pcs on slow days or over night to generate more income i curently have 12 rigs set up and configured them all to work with Guiminner my pcs dish out a avg of 97.3/Mhash

Is this something that is worth doing? acording to some bitcoin calculators i really wont be making anything? Should i take my 12 pcs and connect them to a pool? sorry im just trying to learn soo much so fast and u did say ask me any

I wouldn’t go into it any more than as a hobby.  Although, bitcoins are going up in value.  Connect to a pool. is a good one.  I think the value of bitcoin will go to at least $25 by the end of 2013.
