I am starting planing my build. Parts list:
ASUS Z170I Pro Gaming Motherboard
Intel i7 6700k or i5 6600k (not sure what to go for, watercooled)
SF600 — 600 Watt 80 PLUS with custome length cables
Corsair Vengeance LPX 16GB (2x8GB) DDR4 3000MHz or taking over RAM I already use in my PC
Intel 600P 512GB M.2-2880 PCI-e 3.0 x 4 NVMe 3D NAND Solid State Drive
EVGA GeForce GTX 1070 FTW Gaming ACX 3.0 8192MB GDDR5 (fully watercooled)
LF REACTION 160MM RESERVOIR or M1 NCASE RESERVOIR
2x 240mm slim rad (bottom and side) - not sure yet what to choose
4x slim fans
Goal - silent or as quiet as possible. CPU + GPU + bottom rad and res would be done with hard toobing (what size should I go for?), side res will be ten connected with soft tubing for better flexibility. What do you think about it? Any advices?
That build will not be quiet, or even silent, because of the liquid cooling there's always going to be a pump noise, also you're being ambitious with the space, sounds more like an ATX build. The only reason to do water cooling in the NCASE is for the look. Save money by going air cooling, the system will really be quiet at that point, and spend the money on the i7 and a 1080. Skip the SF600, the 450 is quieter and plenty for the system unless you maybe plan on going for a titan X. Also I'm half certain that the FTW editions are too wide for the NCASE.
