I'm actually amazed you can get 1024 PC mobos all going at once. Many
if not most mobo mfrs turn their designs 4 times a year, that is not
much time to do exhaustive design checks. And the power conversion
circuits are frequently running components beyond spec, so that this
area has a life expectancy of 1-2 years, on many boards. I guess PC
mfrs figure you'll buy a new one by then so what the heck. But it
varies with the mfr and the specific board. I've had some with <5%
failure in 10 years, others 25% failure in 5 years. And dont get me
started on the power supply and the fans...
