New build from komplett

[Orsja]

Hei!

I am looking to get a new pc using komplett . no

I have been looking on this pc:
komplett.no/komplett-gamer-premium-i35-gtx970-edition/10946#!tab:extra

I did do some change on the setup:

changed i5-4690K with i7-4790k
changed Gainward GeForce GTX 970 4GB with MSI GeForce GTX 970 Gaming 4GB
changed Corsair Carbide 330R with Fractal Design Define R4 Black Pearl

Will i get any problem with those change? will it work with the motherboard/PSU?

this will be the spec:

Case: Fractal Design Define R4 Black Pearl
PSU: Cooler Master G650M, 650W
Motherboard: ASUS Z97-P, Socket-1150
DDR3: Crucial DDR3 BallistiX Sport 1600MHz 8GB 8GB kit
GPU: MSI GeForce GTX 970 Gaming 4GB
CPU: Intel Core i7-4790K Socket-LGA1150

Is there any other change i should do? is the motherboard ok etc?
And something that is very important to me is that the pc is quiet, that's why i selected the case with sound isolation.
My budged is max 13999 KR (1623EU/2032US)

I do not know much about computers but i want to be able to play wow on the best settings with little lagg.
Any help would be greatly appreciated!

And should i go for i7 4790k or i7 4790? i will not OC.
And i i think both CPU will come with the intel box fan, will the K CPU overheat with that fan?


Really nervous about buying this PC as it is a lot of money for me, so i just wanna get some other people option

is the MSI GeForce GTX 970 Gaming 4GB PhysX factory overclocked?

This will be the spec of the pc

Case: Fractal Design Define R4
PSU: Cooler Master G650M, 650W
Motherboard: ASUS Z97-P, Socket-1150
PSU: Intel Core i7-4790K Socket-LGA1150
DDR3: HyperX Fury DDR3 1600MHz 8GB
GPU: MSI GeForce GTX 970 Gaming 4GB PhysX
SSD: Kingston SSDNow V300 240GB

Only thing i am not sure about is if i should take i7-4790k or i7-4790, i will not overclock.
And if i go for the i7-4790k will the fan that come with it be ok?
