If it's glued on, just use a pocket knife to pop it off. Stick the blade between the chip mounting point and the heatsink. It should take very little pressure.
That's even better. Just get a pair of tweezers and squeeze the ends of the nails together. It's kind of hard to explain but they should pop out. If they dont come off just cut the plastic nails.
The good part about this is if the holes line up properly you can slap that blue orb on without using any epoxy. The blue orbs come with some plastic retaining pins to match the holes up.
