Well I would be happy to help you friend. I live in America, but there are tools online that I can use to help you figure out a good build in your currency. Check out these two sites: pcpartpicker.com and logicalincrements.com The fist site allows you to put builds together and compare prices of parts, while also giving you build guides to work off of, the second one gives you compatible build suggestions. If you would kindly give me a few minutes, I can see what your 500 Euros can get you.
