No, your CPU may be fine.
Test out of case by only using PSU, Motherboard, and CPU first. Youll get beeps but at least the circuitry in the MB is ok.
For a complete test, only hook up PSU, MB, CPU, RAM, and Video Card.
You will have to use the power switch thats embedded into the case to turn on the system out of case tho, so keep it near the case.
Non conductive surface of course.
