It's nearly always the moving or stressed parts that fail - fans, HDDs and PSUs. The actual electronics just seem to keep going.
Yup thats right. Motherboards seem pretty indestructible these days except the ones that have been built using substandard caps, wish I knew enough to replace these things.
Most memory seems to last forever as well, the best was Crucial, their stuff never went wrong but then they went and released their BALLISTIX PC3200/4000 which lasted about 6-9 months before starting to fail.
The Hard-disk most likely to fail in my book is MAXTOR, the least likey is WESTERN DIGITAL or SAMSUNG, dunno what it is with the Maxtors?
The PSU is the one though, in general I think these should be replaced every two years, some people may disagree but I have seen a heap of computer problems the past 12 months caused either by a PSU failure or even worse when the PSU is half-dead (Undead PSU not nice).
As a hardcore rule of thumb, I would expect that a new component may well be faulty. so if possible make sure you have a backup plan (i.e spare stick of ram, spare hard disk etc). If everything goes smooth and you have no problems then thats a *bonus* just don't expect that things will go smooth
