well, if you have got the experience you could make a custom pcb for the ps3, from what i know of its pretty easy to find the schematics for the ps3....
i found a pdf for what i think is the entire schematics for the ps3, i dont know which motherboard revision it is but i hope it will in some way or another.
but it says reproduction prohibited so im unsure about, i think its only if you're going to sell it after tho....
Admin edit: we can't link/host these files on the forums, as we would like to stay away from extreme legal troubles
for Admin,the pdf shouldnt cause any legal troubles, beacuse its just the service manual. its only if you are going to copy the design and resell it. But i understand the concern
