If the dimensions for the Corsair C70 case quoted above are accurate, fitting the Noctua NH D14 inside this case should not be a problem as it is only 160mm tall.
Get the Noctua NH D14!
Yogi read the review in your link again. Don't just look at the graph, that is a value analysis not performance analysis. If you read the paragraph above the graph if says it did not out perform the H100i but showed at the top of the graph because its cost vs performance was the best as water cooling is generally quite alot more expensive.

"Yielding CPU temperatures just a few degrees warmer than Corsair's top-performing H100i, generating less noise than the extra-quiet Enermax ELC240, and selling for less than any of the closer-loop liquid coolers in today's story, Noctua’s NH-D14 looks like the surprise winner in our analysis of value."
