I would keep in mind that computer parts are very susceptible to static electricity. I would avoid putting any pantyhose inside the computer, they are static magnets lol.

And vacuums also can create static electricity, so I would avoid putting the vacuum hose inside of the case. There are little battery operated vacuums you can buy that are just for cleaning computers, but cans of air are much cheaper.

Just a little static electricity can ruin your day

Anytime you are going to touch any parts inside your computer make sure you ground yourself by touching the outside of the case before you reach inside. And if your going to be changing parts, or building a new computer, try not to work on it while on a carpet.
