Unfortunately the possibility is yes. But based on the way you wrote your OP, is suspect "probably not".
These parts could be bad, and troubleshooting which are bad, if any, could be a time-suck. The only thing out of the bunch that is most likely to damage the new mobo would be the PSU. The other components would suffer electrical shorts, but not "give" electrical shorts (for lack of better words).
To protect yourself, try to buy your mobo from a "friendly" reseller, e.g., one who has a good return policy. (newegg, amazon, etc)
Good luck, and keep us posted. (And keep the liquids away from the system!!
