PC exploded

This afternoon UMM took SMK home PC and install at UMM house.

After connecting all the cable and switch on the PC - "poofff !!!" ... smoke pop out from the PC ...
Gave me a fright !!

What would happen if the PC exploded at NZ ? It may have scared off SMK + kids, it may be too hard to get a spare-parts or maybe too expensive !!

Anyway - send for repair ... waiting for the costings.
