@tyt2009...i work for microsoft Australia xbox 360 repair division...honestly i think u dont knoe a jack abt xbox 360 hardware..manufacturing date doesnt make ne difference as long as the xbox is fitted with the new jasper mobo. Mobos' before jasper had a designing flaw n secondly earlier mobos' were based 90nm cpu's n the gpu's, therefore causing alotta heating issues within the box which was the main factor behind hardware failure(rrod/three rings of death) in the xbox 360. Hope this clears everything up!
