recently I did some xbox modding and came across something interesting. had xbox 1.0 and recent revision and there were several difference between two apart from obvious PSU socket change.
on older revision there is fan attached on GPU as well as CPU but on recent revision there's only heat sink on GPU? Does this mean M$ thinks it can get away with few cents saving from active cooling to passive cooling? Thought the amount of work GPU needed to perform it will need active cooling not too mention the longevity of the console itself? Maybe I got it wrong and passive cooling of GPU is perfectly fine?
also the USB port connectors are now on M/B rather than daughter board on earlier revision.
apart from this there doesn't seem to be too much of change - except the new encode chip used nowadays.
oh,yea. the reason for all these was to put US xbox 1.0 guts into new transparent green housing with Samsung DVD drive. :)
while we pulled apart we also put the mod chip with the switch. this mod chip was one of few Enigmah samples given to us long time ago and required 29 wires to be soldered. We were having fun but wouldn't recommend to every body though. :)
