As for voiding any warranty, should a problem arrise, it's up to the manufacturer to prove that whatever you did caused damage. Just taking apart and reassembling a console correctly will not void your warranty. "Warranty Voided if removed/opened" labels are not legally-enforceable in the US. Just look for Youtube videos on how to take it apart (or look for repair videos for other items in the console).
