Step 1: Decide on your design
This WHOLE mod is centered around a single design. If this is your very first mod to a console, or if you aren't very skilled with a dremel, you should consider a simple shape, such as a rectangle, circle or triangle. Simple shapes are MUCH easier to do than complex ones (obviously)especially if you rarely work with a rotary tool, such as a dremel. Try not to choose a design that exceeds your skill level. Simple designs look good, especially if you take your time. Something like this should be easy enough.
