Smoke machines/generators and computer hardware

Will those smoke machines/generators that uses water and creates a fine mist like the ones used at rave parties and events damage computer hardware?

My problem is that I am a DJ and I use these machines quite often in close proximity of my laptop and computer case. The case is a Antec 900. I'm worried that it may take in an excess amount of moisture from the mist and damage the electrical sensitive hardware inside it.

And sorry if this is not the right forum to post it in, I'm quite new around here.

I'm not so worried about my audio gear such as speakers or the decks since they aren't so prone to static or surges, like the speakers is pretty much a few wires and a magnet.

I'm more concerned for the circuits such as the motherboard or hard drive since they are very delicate components to my understanding.
