From a technorati blog:
"Apple clones creep back on the streets"
"Apparently, the latest thing is a "PowerPC G6 Macintosh", an "Apple G6 Macintosh-Clone Computer" with a 3.8GHz Pentium 4. These come with shedloads of OSx86 compatible hardware, and pre-loaded with something called a "Mac OSX-86 Apple MacOS X Tiger 10.4.3".
The beasts are being made in China and South America, but unlike the real Apple machines, these clones will cost you only $500."
And if you're curious how to get one?
