Customer laws here in Holland describe that opening up a case does not void warranty

To get out of warranty claims, a company needs to proof you broke the equipment on purpose. Opening up a case, is not proof of that, not even glueing the weights or disabling the keyboard. You are allowed to tweak things during warranty according to our laws..
