everybody's experiences will be different because:
- some people buy good products, some people buy cheap stuff
- some people add fans where needed, some people dont
- there are always exception to the rule of "good stuff"
( like ibm's major !@#$% with their deskstar series of drives,
( caused them to sell their entire disk drive division to hitachi
( -- just kidding .. but the timing is good for a joke
given the same system ... things that should die first would be based
on MTBF ... ( mean time between failure ) all rated at 25C
Warranty period is probably closely related to MTBF ...
- fans ( typically no warranty ... )
- power supplies ( some have 100,000 hrs if you believe it )
which confirms Pauls experiences w/ power supply vs disks
- disks ( typically warrantied for 1-3 yrs )
- cpu has an mtbf around 30,000 hrs ( about 5 yrs )
-- notice that your cpu lifespan dies 2x faster for each
10C increase in temp
