How did you cut the heatsink? It came out great!
Cut with a dremel, the same bit I used to cut a motherboard. Then sand it a lot, I used 60-150-220 grit until it was smooth to the touch. Probably don't need to, but I finished it off with some steel wool.
I forgot all about Wii U gamepad shells. This has potential to look very professional. Looking forward to this project.
I've had this shell for over a year now, I just worked on it off and on. My goal was to make it look as stock as possible, but have a Wii inside instead of a normal gamepad. That includes reusing the buttons, speakers, joysticks, etc. The only thing I don't like about it is that the screen on the stock device has a thin plastic bezel glued onto the touch part, but my shell didn't come with it, and I can't find anyone who sells them. I plan on painting the metal shell black, and putting a gloss coat over it to hide it.
