What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.

Gaming mostly, all the games possible will be played

What is your maximum budget before rebates/shipping/taxes?

1000-2000€

When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

Either in 1 month if it's mini ITX or can be carried within a plane 6 months if I need to build part by part

What, exactly, do you need included in the budget? (Tower/OS/monitor/keyboard/mouse/etc)

The case with the needed components.

Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?

Germany and Turkey but Germany is always a better choice when it comes to price but in the end pc will be located in Turkey.

If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.

Nothing is planned about this at the moment.

Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?

I have no experience at overclocking but I will if PC is built for that

Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)

gtx 1080 ti is a must, SSD strongly prefered

Do you have any specific case preferences (Size like ITX/microATX/mid-tower/full-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?

Mini ITX or any size that could be taken to plane as a hand-baggage

Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?

No, it's not necessary
