I'd probably agree. I think Ralf is too paranoid here.
OTOH, if it were me, I'd just download a fresh copy.

Bad plan.
Make a new home, migrate your data.
Ownership & permissions are issues and will ruin your day and maybe week.

Nah. Not worth the effort. I vote against this.

Oh dear. Bad research. You should have asked.

Augh! :-(

Consult thinkwiki.org. Get the measurements.
It's what I did. Not hard. Beware, mSATA is not the same as NVMe.

Ram is the easiest, quickest and cheapest part. Do not postpone it.

SATA 2 vs SATA 3 makes no material difference. You would not be able to tell.
This is nerd point-scoring for gamers, overclockers and other gullible
types with too much money.

Yes, this.

Nothing noticeable. Measurable with sophisticated benchmarking tools only.
Hint: never use these unless you suspect something is wrong. They only
serve to make you unhappy.

Yes, on the HD.
