In the following steps, you will remove the top vent, secured to the top panel by the thirteen clips shown.

Take care when removing the fan vent not to break any of the plastic clips.

Orient the console so that the words "XBOX 360" on the sides are right-side up, and the faceplate is facing to the left.

Insert a metal spudger between the top vent and the top bezel near the rear of the Xbox.

Rotate the spudger away from the console, prying the edge of the fan vent up until the two plastic clips come free.

Be sure to rotate the spudger far enough so that the plastic clips clear the silver rim of the top bezel.

Insert a metal spudger between the fan vent and top bezel along the left side of the console.

In the same manner described above, begin prying the left side of the top vent away from the top bezel.

Continue prying along the left side of the device, freeing all the clips on that side.

Lift the fan vent up from the freed left side to disengage the clips along the right side.

Remove the entire fan vent.

In the following steps, you will be releasing the six clips highlighted in red.

Each clip can be undone by inserting a metal spudger underneath the bottom edge of the clip. Once underneath the bottom edge, simply prying away from the console will free the clip.

Orient the console so that the left case is facing toward you and the faceplate is facing toward the right.

Insert a metal spudger through the front-most slit on the left edge of the top bezel and between the bottom edge of the clip and the left case, as described above.

Simultaneously rotate the spudger away from the console and pull up on the top bezel to free the clip.

You will hear a "pop" signifying that the clip cleared its catch.

Using the same method described above, free the two remaining clips along the left edge of the top bezel.

Grab the entire top panel with your hands, lift up the entire left edge high enough to rest the separated clips on top of the left case.

You may have to go back with a spudger and undo any clips that have re-attached.

The top panel will not come free of the console yet.
