Will you still be able to get hardware support and repair parts 10 years out? 
And even if you can, you may reach the point before 10 years where it would be 
cheaper to replace than maintain.  If you are paying for support, that's just 
going to cover repair/replacement of the nearly obsolete component - and newer 
equipment takes a lot less power for the same capacity.

I'd consider 5+ years to be a reasonable expectation - 10 is possible but a 
stretch.  You'll definitely be exposed to new security vulnerabilities that may 
  be discovered beyond the update support cycle on the OS so it doesn't fit in 
any sort of "best practices" concepts, especially if there is any 
internet/remote exposure.
