What risk?

Have all of your self assembled PCs worked right out of the box? I've
built more than a few myself, the vast majority of which worked just
fine. When they don't though, you are on your own for troubleshooting
and problem isolation. If you buy pre-assembled and it doesn't work
all you have to do is call up and get a RMA number.
