Styrofoam is a bad idea it tends to have a static electrical charge especially when moving around. You are going to need to find something else to pad it.
well, what if I had fabric over the styrofoam, would that make a difference. I just want a light material that I can attach the components too. I was originally going to use wood but was kind of heavier than I would like. Any ideas or suggestions please.
You'll still have the problem with fabric, you need like some sort of plastic, wood, or metal.
So, what if I instead use a metal wall/old PC side panel and put fabric around that with of course the motherboard attached to the metal. Might this be a solution to not shocking the motherboard? Thanks for your help so far

Anything fabric on fabric with the motherboard and electricity is a BAD idea. You have infinite potential to pick up an electrical charge.
To be honest trying to put a PC in a canvas backpack is a bad idea in general. Way too much movement, you can't safely have a CPU cooler in there, you have to carry a fairly large PSU, and get it to run on a battery which will be heavy as well.
