The location you describe as hot is where the psu sits. Try to take it to someone who can test all the voltage rails, maybe something is gone bad. I had an similar problem on a late 2009 27" i5 iMac, but we figured out that GPU overheating was the cause (this machine shuts down when the gpu die hits 80 degrees Celsius).
