Ha ha... yeah... change that.
Anyway, if you're somewhere where there's a lot of static (carpet, dry, etc.) you may want to get an anti-static wrist strap.. they're only like $5. Clip it to your case, and you should be fine.
However, most people will just tap their case every once in a while (make sure to tap/clip to the metal part) to ground themselves. Do it often, though you don't need to constantly hold it. Make sure static bombs (pets, children, especially furry cats...) don't get near your workspace. Don't set your motherboard on the anti-static bag it came from, set it on top of the cardboard box it came from. Always ground yourself in between working on the motherboard and doing something else (say... opening a box).
Anything I missed?
