Thanks for coming to the forum. If you are looking for tutorials you should check out the
Wii Trimming Guide.
If you are looking for a complete step by step guide for everything in a single tutorial, you are out of luck. There are guides for various aspects of portabilizing (such as trimming and powering the wii or making a
case) but I would suggest you lurk more in the forums and go and read all of the posts about the wii. Coming here and asking a question without doing any research won't get you very far.
Everyone here is willing to help but they aren't willing to hold your hand and powder your bottom. If you are really a noob for everything then start doing your research. If you know nothing about electronics check out
this thread.
