ok i have just orderd a new pc, on the FAQ it says if i add a component the waranty is not void but it does say this

You understand that we have over 30 different measures in place to detect if a component has been moved/removed and if you have moved/removed a component, your warranty will be void. You are only entitled to add extra components to your computer.

so can they find out if the component has been moved/removed or if after adding a new component my pc get messed up and i take off the new component and the pc is still messed up?
