Hi. I'm going to be getting a Wii soon, but I'm perplexed about one thing: I have a wired router, and it would be nice if I didn't have to buy a USB ethernet adapter. After looking at this page, I have come to the conclusion that it is very likely that it is possible to replace the Mitsumi Wi-Fi card with a Mini-PCI ethernet card. Notice the ugly-looking card in figure 16. How disgusting! It looks like as if somebody poured grey goop over the mini-pci card!!! After all, if it needed to be returned to Nitendo for repair and/or replacement, I would just put the (ugly) Mitsumi mini-PCI card back in place of the ethernet card before sending it back. Also, why would the processor need a heat sink? I thought the 750CX processor produced so little heat that one would be unnecessary.
