حوار مفتوح.. انا اسال وانتو جاوبوني

Recently I purchased a Wii console and I have some questions:

1. I have two original Wii Remotes and want to add another 2 extra remotes. Does anybody have a good advice for 3rd party remotes (the price for nintendo's sucks)?
2. I want to modify my console I can run backups, I am totally novice , any suggestions?
3. What tools do I need to open up the case?
