Step 6: prep the case
the main modifications you must make are hole for the speaker and trimming some unnecessary plastic bits.
first step, grind down the ring on the back case , once that is grinned smooth use a power drill and drill a circle pattern like i did where your speaker will fit. then grind the post on the right that help support the circuitboard that helps make room for the record button then drill a hole where you would like to mount the reset button.
now on the front pannel grind down the tabs on the d-pad and glue the d-pad in place let dry.
