In many game tests that I have participated in, there was the ability to update your application with your computer specs. Or sometimes you would just reupload a new dxdiag file. It really just depends on if, and how much, they are actually interested in your specs or not. In SE's case, all evidence points to it being quite a low priority, if one at all.

In any case, right now they shouldn't be interested in anyone's specs. They are just stress testing at the moment. If your rig can power on and sign into the game without crashing, you meet their requirements at this point.
