I can't decide if I am going to buy a phanteks enthoo luxe or a corsair 750d for my build, I chose a full tower because I need a case that 3 5.25 inch drive bays, also just for reference the phanteks enthoo luxe only support gpu's up to 347mm and that might not be enough for future upgrades. Overall my question is which one of they cases is better for low temps and high airflow?
Here is my build

Both cases are excellent from a airflow point of view.
They each support two front 140mm intakes which is enough for the hottest cpu and graphics card.

347mm is 13.6 inches and more than enough for any modern graphics card.
Your selected card is one of the longest at 12.13"
No problem there.
Future cards can be expected to use smaller lithography and will not need so much cooling.
Actually, fancy graphics coolers sell better even if they are not needed.
That is why you see so many.

I do think for a build such as this, you are short changing yourself with such a modest cooler.
Your cases can support tall twin tower air coolers of 170mm or more.
One of the very best might be the noctua NH-D15s.
If the excellent noctua 140mm beige fan sandwiched in between the towers bothers you, you could replace it win something else.

If you have already ordered components then it is fine. If not look into this build. Lot more powerful and better quality build.

The Phanteks Enthoo Pro case is good and supports all your requirements.
