How to get 4 layer wii motherboards?

[Another]

Hey everyone,
To be able to build a wii boy you need a 4 layer wii motherboard to trim it down.
I've been looking for one quite a while now with no success. Since the Gman kit rev3 is selling so good people must have found a way to get them easily. So if anyone know how to get one please let me know I'm dying to build me a wii boy.
Have a great day and thank you for your time.

You will have more luck by buying a colored wii on ebay. The white wii's are hit or miss. I bought a pack of two black wii's and they both were 4 layers. Hope that helps.

Also look for Wii’s without GameCube ports

This basically says the same thing that the other two people said, but this page in the Guide Hub explains all about the differences between 4- and 6-layer boards and how to identify them.
