the mainboard is bad on my Wii. so i decided to send it back to Nintendo for warranty repair. i only had it for 5 months. it should still be in warranty. since i installed a wasabi chip, i know i have to take it out. so, my question is: if Nintendo voids my warranty how much do u guys think they will charge me? by the way, where can i get the white stickers that cover the screws on the Wii?
