Modding your Wii can cause a brick. Kids can disable your system completely. I'm sorry.

Anyway, a Wii costs ~130 Euros now. If that would happen - and chances that this will happen are very low - you'd throw your Wii away and buy a new one. Your games are save on your HDD and NAND, and you should make a backup of your NAND once in a while anyway.

I updated my Wii to 4.3E and started modding them. That's the easiest way. Use Letterbomb to get the homebrew channel, and then you install some stuff. That takes ~30 minutes.

I'm sure Kiekoes will post you a tutorial, he wrote one. Don't worry, it's not difficult. Even a retard like me can do that.
