Build the PC by yourself = you can choose components that you need, also save some money (components for that topdata PC would cost +- 6900kr., but it`s not the most important, the most important is own configuration).
Components for you, i assume that you gonna OC one day, PC will be silent (with a possibility to make it ultra silent - using software to reduce cpu cooler`s speed, using R4`s fan controller to set fans @ 5v or 7v, there`s also 12v option):
1. cpu Intel i5-4670K:

3. RAM - 8GB 1866MHz CL9 (pick one):

- so you got free delivery and prices for those components are nice there, maybe you can find also other components, which has nice prices there.
PC will cost +- 8800kr.
You can always buy HDD later - if more space needed (WD Green 1TB as a "lager disk" will be fine and is a silent one - WD10EZRX model).
Why not GTX 780 OC? - it gives you +- 13% more fps than GTX 770 OC for 1200kr. extra, kinda not the best deal, and changing gfx is just a piece of cake.
Other components - are great, so the only thing you should thing about - for the future - is HDD (if you need more space), and gfx (but ... in like 1,5 - 2 years time).
