Hello, I'm going to be building a PC hopefully next week, here is what I'm currently looking to buy:

CPU: Intel i7-8700K
GPU: ASUS ROG-STRIX GTX1080TI-11G-GAMING
CPU COOLER: Corsair H115i PRO RGB water cooling
RAM: Corsair Vengeance RGB 16 GB (2 x 8 GB) DDR4 4000 MHz
MOTHERBOARD: ASUS ROG STRIX Z370-E GAMING
PSU: Corsair Platinum Series HX750i 750W
STORAGE: Samsung 850 EVO 500 GB 2.5 inch Solid State Drive
MONITOR: Dell S2417DG 24 Inch TN Gaming Monitor (Black) (1 ms, QHD 2560 x 1440 at 165 Hz, Nvidia G-Sync, DP/HDMI/USB)
CASE: Phanteks Evolv ATX Tempered Glass

Is there anything you think I should change / look into? Also how should I overclock the CPU, I'm not really too sure what voltage I should be putting it at etc.. Any guidance would be greatly appreciated!

I'm hoping to overclock the CPU

IMHO NVMe drives are still too expensive for the benefits you get over a normal SATAIII SSD. I'd rather have a higher capacity SATAIII SSD than a faster, lower capacity NVMe drive.

You sure you want a 4000mhz RAM kit? What is it's DRAM voltage in the XMP profile? Aside from being very expensive and not offering much more real world performance than say a good 3200mhz kit it will likely be a pain to get working properly. It likely wont be as easy as just turning on the XMP profile. I wouldn't recommend a kit faster than 3600mhz 1.35v for a normal gaming PC, 4000mhz kits and above are typically bought by overclocking enthusiasts not people looking for a stable and reliable gaming PC.

Looks like a very solid build IMHO.
You could save a little by going with a smaller PSU. Unless you are planning on running two GPUs, you don't need 750 watts. A good QUALITY 550-650 watt unit from tiers 1 or 2 here:

would be more than enough

Ok, the MB supports 4000mhz RAM. I'll have a look into RAM and how much of an affect it will have. Thanks very much for the response, let me know if there's anything else you think I should change.

The mobo can theoretically support 4000mhz but like I said it be as easy as just installing the kit and turning on the XMP profile. You will likely have to screw with timings to get it stable or even to boot. A kit like that is not ideal for a normal use case gaming PC. That is the ragged edge of what your motherboard and CPU memory controller can support. Intel recommends no more than 1.35v DRAM voltage to ensure a long lasting cpu memory controller, that 4000mhz kit is likely 1.4-1.45v.

Ok, I'll have a look into some lower W power supplies thank you. What do you think about my SSD? Should I go for an NVMe instead?

Ok this is great info thanks! Seriously helps a lot. I've just looked at RGB Corsair Vengence 3200mhz, it says its tested voltage is 1.35V (which is good I guess?). If I was to get this 3200MHz RAM would I be able to use the RAM at 3200Mhz or would it struggle to maintain it? This was the main reason why I wanted to get 4000MHz so it could handle lower MHz easily / steadily, I'm probably wrong with my logic here haha.
