Please review before i pull the trigger

This would be the config for quietness and performance with some consideration for ease-of-build:

Swapped from the liquid cooler H100i to the air tower Scythe Mugen 5 (Japanese for Unlimited/Limitless). The Mugen 5 is ~$46.99 on Amazon but seems to be perpetually out of stock there for the time being. It has 90-95% cooling power of bigger air tower and can match or be within a few degrees of many 240/280mm AIO (include both the H100i and the X62) while producing somewhat less noise compare to air towers or practically zero noise compare to AIO liquid rad. Plus it also have an asymmetric design that allow full RAM clearance.

ASUS Maximus IX Hero with better VRM that will allow you to choose between going for high OC (5Ghz+) or lower voltage to CPU (and therefore lower temps) at standard OC (4.7-4.8Ghz).

Kingston Savage 2x8GB 3000Mhz for being low profile dual-rank modules. A pair of Savage give Kabylake CPU four ranks of DDR chips resulting in higher memory bandwidth than a pair of single rank modules even if bus and CL specs are the same (this is a characteristic of Kabylake/Skylake memory controller; the same effect could also be achieved with the cheaper single rank modules, but with four DIMMs).

Storage configuration is a SK hynix SL308 500GB for OS/games, a WD Blue 1TB 3.5" 5400rpm for secondary storage (music and most frequently re-watch movie or YT clip) and a WD My Book 4TB USB 3.0 external drive for movie storage, recorded game footage, back up, etc. The external drive don't need to be connected to the PC all the time while the 5400rpm WD Blue is selected for minimizing noise and vibration; lastly, the SSD just don't make any noise in operation so the build would have virtually zero noise coming from the storage hardwares.

Unless you're like this guy who have ~1400 games on between Steam and GOG, ~400GB (subtracted OS, etc... from the stated capacity) worth of games on the SL308 will be more games than time you have to play them all. You'd still have many storage upgrade options available with one 2.5" SSD bracket, a 3.5" HDD bracket on the P400S and both M.2 slots plus a PCIe 16x wired for PCIe3.0 x4 bandwidth on the Hero when you need some extra TB to cope with the games bloat out to more GBs/game. If you actually have lots of music/movies/clips you want to have ready-at-hand then just swap the 1TB HDD to the capacity that match the size your library.

Since the build no longer has a liquid AIO, swapped the case back to the P400S (extra sound dampening) and swap PSU to the be quiet! DARK POWER PRO 11 850W. The DPP11 850W is a bit excessive for the build, but the low load on the PSU by this build will allow the PSU fan to stay off virtually 100% of the time (and even if it does come on, the Silent wings fan used in the DPP11 is the quietest PSU fan around). Plus its PCIe cable are the AWG16 thickness which would guarantee zero issue with powering both 8pins of a hefty OCed 1080 Ti with just one cable (Use PCIe 1 plug on the PSU for the first card; use PCIe 3 on the PSU if/when doing a SLI config).

Two extra Phanteks F-140SP fans (larger diameter fans = lower rpm = less noise for the same amount of cooling) to be mount as intake while the one 120mm included with the P400S at the front could either be removed or relocated to the top.

Dell S2716DG 27" 1440p 144Hz Gsync with good color reproduction for TN panel and very low input lag which will be great for gaming.

Finally, W10 installation that come on a ready-to-use USB ($109.98 @ Amazon or use the PCPP link and deal with $114.88-$10rebate+??Shipping @ OutletPC) to simplify installation process and you're getting a retail license instead of an OEM one (MS support, transferable to a new build, vs self-help and license tied to MB).

If you really want some RGB with the TridentZ, look for way to control it using ASUS AURA because the TridentZ RGB beta software can kill your RAM. Last note for your RGB desire : Phanteks RGB LED Strip Combo Set.
