This is my spin on the GCDual HDMI port drilling jig. This helps you to drill out most of the HDMI port hole with proper alignment. To use it you simply orient it so the first set of 3 holes line up with where the HDMI port hole is supposed to be cut. Drill out each of those 3 holes, then rotate the drill block so that the side with 2 holes lines up in between the 3 holes you drilled previously, then drill out those 2 remaining holes. After that use a file to square up the hole and adjust the final shape and fit of the hole for the HDMI port.
