Let me help you with that formatting.

PCPartPicker part list / Price breakdown by merchant

I would say 32GB of RAM, that power supply, and having an Sata SSD and an M.2 SSD are all overkill.

Also, don't know were you are planning to get an OEM copy of Windows 10 for $28 dollars, but it's most likely grey market at best.

yes, you can put the cooler in the front. top exhaust fans in this case don't do much, the top exhaust ports are so very tiny after all, more air bouncing off the top panel and going back into the case does nothing to improve temps, in fact achieves the opposite result. this all looks good and well, but a few things need be corrected, because they aren't quite "correct"in a would be premium build.

• the Z170 MPower Titanium looks nicer than the Xpower, but the pci-e slots are so low on that board, SLI in a mid tower with 7 slots and a solid mid plate/basement cover is going to be tight and uncomfortable. with this motherboard I suggest reference cards that exhaust out the back of the case.
• I recommend a smaller M.2 drive like a 256GB 950 Pro and a 1-1.1 TB Sata SSD like the MX300, Mushkin Reactor or 850 EVO (not really worth the premium over the other two though)
• the HXi 850 is in fact unnecessary even for 1080 SLI. a 650 watt would handle that setup with much ease and breathing room. the Seasonic Prime 650 or 750 at most, is what I'd suggest.
• finally, no way, no way you're gonna pay $700 for a 1080p monitor, an AMD freesync one at that so the adaptive sync won't even function with your gpu.
