was upgrading the harddrive in my imac and everything was great until one cable caught and when pushed into its seated area it broke of the logic bored oh no i only got the machine on thursday

OUCH!!!!!! Did you just say the logic board broke? I don't think AppleCare will cover that :(
 
OP, post detailed picture of this broken connector and that part of logic board where it was mounted. Probably, as written above, it could be soldered back.
 
Have not deal with recent iMac, but applies to MacBook Pro.

Was it connected via a black plastic piece? Those black pieces are designed to come off and snap back together.
