funny thing is i had a 1st gen xbx 360 elite last up until last year when it finally kicked the bucket, when the power supply went, but the reason I think it lasted that long is i didn't put it in a hot box (ie putting it in a entertainment center with a closed door, I put it out in the open where it could get good air flow just liek i do with my pc's, also took it apart and cleaned out the dust every quarter
