These are the things that affect the experience of interacting with the computer and make it pleasing or not, rather than a 5% difference of boot-up times.
If you have genuinely decent parts from the old PC then certainly re-use them, but if they are more than a few years old you may be surprised what a difference of new quality components can make. This is also certainly true of the soundcard.
That said, none of these items will help your benchmarks....
