500€ Gaming PC (my first one)

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

Mostly gaming(overwatch,diablo,civ..)

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

500-530 €

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 Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

A month from now at most

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

Only a tower

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?

Frankfurt/Germany

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

Hp pavillion 23" monıtor Rival 100 mouse Red dragon karura keyboard

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

No idea what it is i am open to suggestions

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)

Again i am open to suggestions

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?

İ dont want it to be expensive but if you can find a cheap case with blue/white led strips it would be cool

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

I don't need a copy of windows.
