If you can wrench on cars, you can easily put together your own computer from all the shelf parts for cheaper and much faster than you would buy in a box. Just find a phillips head screwdriver and go to work. It amazes me when I read stories about hardware defects in brand name computers. I think I've had my server running for over a year without ever requiring a restart, but then again it's running linux.

Again, if you can DIY on a Benz, throwing a computer together is child's play.
