I really doubt there is anyway you could mis-wire your mod and cause sparks with the unit starting up in any way shape or form. If it was that jacked up that it was gonna spark it would be most likely from the power supply getting messed up, not the motherboard. You would smell the sweet smell of burning conductor long before sparks and like I said, the unit wouldn't have worked in the first place.
