No, i don't think 10 years is over kill too much. You of course will be replacing hard drives and maybe ram as you go, but if you get good hardware and take care of your machine, I wouldn't be surprised if the computer lasted you 10 years.
I've got a computer that was well over 5 years old before the PSU blew out. I thought it was the motherboard so I finally replaced it. Haven't tried using the old stuff since I got a new PSU though. But I wouldn't be surprised if it worked fine.
My wife has had a MacBook Pro she got 4 years ago, and it's better than almost any new laptop I've used/seen that cost under $1k.
