Good choice on CPU cooler, that thing is nice and quite.
If you want budget whisper quite, try the ARCTIC COOLING Freezer i32 CO, it shuts off the fan completely when the computer is mostly idle.
When the gears are kicking, fan will run at 32db vs the 21db, but it may not even matter at that point when you're overclocking, 'cuz your GPU and CPU fans will be kicking at near max when you're pushing the system hard.
As far as the Geforce 1080 or even a 1070-
Not a fan of the reference card(s), which personally, I would almost get anything but an nVidia reference card 'cuz of paperweight restrictions and stock mediocre cooling systems.
I'd stick with the 1080 over the 1070, because in some games that run on 1440p, might as well go all the way and get your 144-Hz 1ms ULTRA-settings gameplay, especially if you're shelling out for that extra nice Dell monitor. If it was a 'regular monitor' then I'd drop it down to the 1070 for the 60 fps.
16gb RAM for overclocking might be easier than 32gb on DDR4 'cuz of high latency, especially if the sticks are 16gb x2.
reason to do 32gb is if you absolutely need the multitasking reservoir to be available, otherwise 16gb is fine for 1440p gaming, as of 2016.
