Although precaution is always good, I can tell you, from fisrt hand experience, that computer compenents are more durable/protected than you think. (Oh boy, I've been waiting to tell this story.....) When I was either fourteen or fifteen when my parents decided to get a new computer. They kind of put aside the old one so I decided to open it up. I really liked the case it came in so I decided to try and put in my own computer parts inside. I also decided to do this ALL ON CARPET FLOOR. So basically I had two computer's worth of parts spread out on the floor, trying to figure how to put the computer back together again. My HDD was smaller than my parents old computer HDD so I decided mounted by HDD with boxing tape!!! And when I thought I was finished, the wouldn't computer turned on. That seriouslt scared the crap out of me..... My dad ened up puting my computer back the way it was and it still worked!! Anyway, I kind of learned my leason from that and now I'm a lot older and wiser.
