Had a nearby lightning strike, "scrammed" my Mac, but couldn't start it up afterwards. Google led me to the ifixit site ( where I should have gone first!) and your instructions got me going again. Granted, I had an identical, spare Macintosh so I was able to pull that power supply to replace the damaged one and not have to wait for a replacement, but your step-by-step made the swap fairly easy! Thank you! I am happy tonight!

Now to order the replacement.
