I always hear from numerous people saying that it's not good to turn on and off your computer everyday but not really sure why not to though. Does it ruin the motherboard or something? I got my G5 up and running on Friday and I haven't turned it off since. I'm planning to turn it off once a week. I put the computer to sleep at night to save energy. I would just like to know what other people do and what their setup is. What are your settings for "Energy Saver"? and how often do you turn your computer off. Thanks.
