I found my fans and am about to get some thermal
grease and a megohm resistor for static discharge.
Sometime today or tomorrow I will likely
open the case with fear and trepidation.
The sides and top of the case are metal, but painted with an insulator.
The front is plastic.
The back is metal.
I expect I should touch that before opening the case.
What about after?  Is there something else I
should touch before trying to edit its guts?

If thermal grease is the problem,
how do I find out and how do I clean off the old stuff?
I've read that just adding more is not a good idea.
If I add to much thermal paste, what do I do about it?
