I have been setting up a Mac Mini to use as a home theater PC and media server for my house. I would like to be able to have it running and watch movies from it in our motorhome while traveling, but I'm a bit concerned about the hard drive. How well would it hold up to the shocks and vibrations of the road? It's a late 2009 model, with a freshly-installed 750GB Western Digital Scorpio Blue hard drive. Any thoughts?
