An Xbox 360 is relatively easy to repair once you know how to. The materials that you will need are a Phillips screwdriver (drill is optional), sharp nose pliers (not pictured), 5mm plastic washers, 5mm metal washers, 5mm screws, Arctic Silver 5 thermal compound, and a torx star shaped screwdriver to fit the screws.
The first step is to take off the outer shell to access the parts. You will start doing this by removing the face plate on the front of the Xbox. This is best done by pulling it outwards while grabbing the bottom of the plate.
