I have moved mine myself and had them in the moving van. As far as heat in the moving van, I wouldn't be too concerned unless it broke down in the desert for a few days, because honestly, how do you think the computer got from where it was manufactured to where you bought it? Not in a climate controlled environment, for sure! Seriously, when the movers moved mine from GA to AZ, they wrapped and wrapped each part very well and packed them into boxes that were full of packing material. I think the best thing would be to back up everything you don't want to loose onto CDs or Diskettes, and take them with you. GOod luck with your move, I just did it in December (2600 miles) and am doing it agin in June.
