well, I'm flying to chicago to deliver this piece of new machine I just built. I'm taking the PC on-board, and don't plan to remove any hardware from it, even the HS - especially after talking to many people; I decided that the case will be on it's side most of the time so the heat sink will point up. Are there any precauseions I should take...like leaving the case open for the inspectors to see if my PC is not a bomb, etc. Will the scanning equip erase any data on my hard drive?
