If the concern is about heat and noise, the cooling system is the most important factor, oddly I don't see it even mentioned.

Get a huge cooler like Noctua d14, and you pc becomes silent. It lasts forever, requires no maintenance, a good investment.

If you are adventurous, watercooling is even better, but its a can of worms I decided I'd rather live without - possibility of leaks and cost make it harder to justify
