It can be done for normal user data, BUT, know data is stored on your HD that is not accessible by normal means or by a Windoze based OS. They only way to destroy it is to take a big Ford wrench to it. Which I have done before. About the only CPu that does not have a spy co-processor are ARM CPus. Though from what I can tell, the most powerful one you can get for a reasonable price is about 1/6th as powerful as a 2013 core-i7.
If you bought Windoze installed on your computer, that CPu # and Windoze # is staying with that HD# forever.
