Actually, first you should keep your 360 flat anyways coz if its standing up its more likely to scratch your discs. And also, if you take your big gigant power supply, considering you can lift it (
), take like books, or like 6 game boxes and depening on which you use put either 2 books under each end of the power supple, but only so the very edge of the book is on it or take 3 games boxes under each side of the power supply and make sure that theyre on the very edge of each side. And make sure your putting the books, game cases on the long end of the power supply, not the width. Trust me, it works.
