I'll hazard a guess that your drive, and motherboard, mightn't have a
10 year lifespan. And even if fault-free, mightn't be useful in 10
years, either.
old system:
first hard drive - 4 years; replacement - still going.
monitors (dual-monitor desktop) - one lasted 5(?) years, the other
still going.
everything else - original components still going.
So you're right about the drive.
After 12 years, still not aware of anything I can't do other than 2K
and higher video, and better-than-24-bit color.

I would guess that 1 gig is still enough for systems for the next few
years if you don't use nVidia, maybe double that size if you do. And
you have a whopping huge drive, so you don't really need to worry about
it.
I'll try to re-work the numbers for the no-nvidia case.
With the numbers I have now, another interesting number: it takes 4
years (rounded) for the space use to double.
When I posted the above, I forgot something. The numbers I reported in
previous posts are based on the old desktop "bare metal" install that I
did in late April of this year, a-f-t-e-r I removed the nvidia graphics
card. So the numbers are already non-nvidia numbers. Also, mathematically,
* doubling time does not depend on starting size.
* growth (as a factor) after specified amount of time does not depend on
starting size. If something is 'G' times bigger after 'Y' years, that's
true whether the starting size is 100 or 300 or anything else.
If there were an nvidia card in the new desktop, then some of the math
changes. The current and old "kernels" each become 100 +
non-nvidia-kernel-size; the "rescue" probably becomes 100 + (2 *
non-nvidia-kernel-size). The new desktop has a Radeon card, not an
nvidia card.
