~600-750€ gaming PC (more info inside)

So , I am now looking for someone to help me assemble my own PC . I am focusing on a gaming PC which should be able to play newest titles on atleast high settings. I have found a website , which will put thogether the components and I would be glad if some of you could put the PC together which you would buy with my budget. If you have some suggestions or advices for me , please tell me , I am a bit afraid of putting everything together myself.

Here is the said Website

Normally you should be able to translate it in Google Chrome.

EDIT: I live in germany. Many things in the cookie cutter builds can't be purchased here.
