I've been wanting a change from the Wii's iPod-like white for awhile now, and I think a replacement housing would be great. How hard is this to do? I have experience disassembling the Wii right up to the disc drive (for my modchip). Does it get more difficult from there? Also, it would be great if someone could link me to some good quality shells. I've seen the chrome one, but are there any alternatives?
