I agree with below, but its quite funny.
For a start my second language is spanish and he was definitly speaking it.
The next thing to point out, is that this was definatly a setup, when the computer screen was visible you saw a picture of the umbrella logo from resident evil and it was not from gameplay, it was a picture, also he noticed that the camera could see the screen and he sorta pulled of a smirk and pulled the monitor around, this is not the type of thing that you do when you rage against the computer. He also smiled at he camera when he walked away, this aint the type of thing you do when you smash up your PC. Also i have watched the original video of german kid going bonkers towards his PC and that was not setup, as you can see when he smashes up his keyboard and throws the monitor on the ground, then he notices he is being filmed from the doorway and then picks up the speakers and launches them in the cameras direction then grabs the camera and you see it being thrown through a window.
If this "german" boy was in a rage of this proportion why didnt he do this in the original manner.
