Avoiding Sweatshop PC Components?

Jimmy asks: "Is there such a thing as a guilt-free PC or components? From what I've been reading, third world sweatshops are contracting just as much assembly work to the big-name hardware suppliers as the unscrupulous clothing/fashion industry. I'd love to have a PC which wasn't made off of the back of some underage girl working for pennies an hour. What about it? When is our new-groove techie conscience going to kick in?" Such concern is commendable, but it's not like Dell, Gateway or any other manufacturere advertise this fact in their Press Packets. How does one go about finding out such information and when you do, instead of just boycotting, why not go public?
