I put styrofoam on my case..ESD?

[Anoos]

Hi, I just recently moved and planned on packaging my PC. I tried to get it back into its case box, but I failed. While attempting to cushion it I, like an idiot, put the case's Styrofoam protectors on the sides of it.

It gets dumber, It didnt fit properly, so I cut parts of the Styrofoam off.. -_- Little bits of styrofoam got everywhere, not sure if it got into the PC or not.

Its been about 2 weeks, everything seems to be working alright. So no BSOD, no dead parts. Im replacing my case soon..but

1. How dangerous is styrofoam ESD wise?

2. Am I an idiot?

3. Could my parts be potentially damaged by the styrofoam?

The foam came with my PC case. Is Styrofoam a semi conductor?

EDIT: I Just realized that styrofoam is an insulator. Still, I heard about styrofoam frying RAM sticks during shipping back in the golden days...

I think you are OK. Open the case (both sides) and blow out as much residue as possible with a can of compressed air. But don't force a hard blast close to the board. The force can dislodge small components.

The only issue would be if the Styrofoam managed to rub against another piece or something else and build up an electrostatic charge which could harm electronics if that change was released into them. Regardless if there was any electrostatic charge or not.... it should not damage the electronics inside the case since the case should of acted as a metal shield which would catch and hold any charge, this charge would of been discharged as soon as you touched the case. Do make sure the inside of the case is free of particles though since you don't want any charges building up inside of it (still unlikely though).
