How did they made it ?
Both of them work in Chinese factories and used their infrastructures to have the "PS3 factory like" pictures, and used the tools of the factories to build the fake PS3.
By the way, they told us the hardest thing to do was to introduce a camera and take the pictures into the factory without being caught.
Then they made a motherboard on the basis of an old Atari console, and managed to make it work on a TV with RCA cables. So this was just a PS3 that could play old fashioned Atari games. Total cost : about 280$.
