This step is really only if your background color is something other than black. I am repeating step 4. Select the layer that you flood filled with the "Gray" gradient. Then Selections > Select All back to Selections > Float then again Selections > Invert. Now select the layer you just blurred. Grab your "Eraser Tool" again and start dragging your eraser all around the area we just blurred.

Create a new layer. Layers > New Raster Layer. Now grab the "Rectangle Selection Tool" again. Make a slightly smaller selection near the bottom of the content box. Flood fill this with a light gray. I used #C0C0C0. Then like before, Selections > Select None. Then Adjust > Blur > Glausian Blur This time set the Glausian Blur radius to 15.

Go ahead and do the same bit with the "Eraser tool" again to. Select the layer that you flood filled with the "Gray" gradient. Then Selections > Select All back to Selections > Float then again Selections > Invert. Now select the layer you just blurred. Grab your "Eraser Tool" again and start dragging your eraser all around the area we just blurred.

Create a new layer. Layers > New Raster Layer. We are going to repeat all of these steps again. Using your "Rectangle Selection Tool" make a small selection across the top. Flood fill it with a light gray #C0C0C0.

Now Selections > Select None. Then Adjust > Blur > Glausian Blur This time set the Glausian Blur radius to 15.

Select the layer that you flood filled with the "Gray" gradient. Then Selections > Select All back to Selections > Float then again Selections > Invert. Now select the layer you just blurred. Grab your "Eraser Tool" again and start dragging your eraser all around the area we just blurred.

Around this time I decided the edges needed something. So I added a "Cutout" effect. Select the layer that you flood filled with the "Gray" gradient. Then Selections > Select All back to Selections > Float.

Create a new layer. Layers > New Raster Layer. Add the cutout Effects > 3D Effects > Cutout. Use these settings.

Create a new layer. Layers > New Raster Layer. Use your "Rounded Rectangle Selection Tool" and make a selection inside of the metallic content box. Be sure to leave some extra room at the top. Then Selections > Modify > Feather. Set the feather''s number of pixels to 2.
