Hi! So I've already built my pc and the plastic is still on the motherboard but on the left side where the plastic is commonly found and I don't know if that's bad or not? Don't feel like taking out my gpu and a fan just to remove some plastic. So what should I do? (I have had my computer with the plastic for 4 months and no problems, plastic isn't melted or anything looks fine.
 
If I am looking at the motherboard correctly that "r" shape is in fact the heat sink for several components - most notably the VRM. The VRM typically gets very hot and thats why some of the nicest motherboards include a modest heat sink. Plastic is like a blanket. Turn off your computer, unplug the computer, remove the fan and video card and take off the plastic.

Why risk your motherboard and possibly the rest of your components over a procedure that should take less then 20 minutes total?
