I suggest using a magnetic screwdriver. It comes in handy when you need screws to be in certain places. It won't harm anything, so I do not see why anyone wouldn't use it.
Looks good but you don't need Vista Ultimate. Save some money and get Vista Home Premium. There are no differences in performance, there are only a few added extras that you probably wouldn't use anyways.
Thanks gt7, I normally would have gotten Vista Home Premium, but the Ultimate was only $20 more, and I figured that was worth it for the complete backup program it has.
