Hey!

I'm currently looking for parts for my rebuild of my current setup. I'm planning to keep my GPUs, if this sounds silly please let me know. My current build is the following:
ASUS GTX 780 3GB OC x 2
i5-3570k
8 GB RAM
Cooler Master V1000 - 1000W PSU
256GB 850 samsung pro SSD(OS)
2 tb external storage

I'm planning to keep both the storage units, the PSU and the 2 GPUs unless there is advised otherwise

I haven't made up my mind yet about all the parts, but I've currently been looking at following
NZXT H440W
MSI Z170A GAMING PRO CARBON
Intel Core i5-6600K 3.5 GHz
Kingston HyperX Fury DDR4 2133Mhz 8x2 GB
Corsair Hydro H110i V2 High Performance CPU Cooler

Please advise or suggest parts that I should or shouldn't use, thanks in advance!
