My first PC build compatiblity

Yes, I think that will work, idk get an expert. :) Anyway, 3 fans should do. The stock fans and coolers should work, but if you are overclocking get a better cpu cooler than the stock.
 
That PSU probably won't translate over to Poland. Most of that build looks pretty decent but I don't see a GPU listed. Are you going to be using it for gaming or not?

It's always better to buy locally than internationally as your build will meet power requirements for your country that way. If you don't know of a store that you are going to buy from you can find one from the link in my sig.
 
Thanks, g-unit1111, for your reply. All these parts are available in Poland in the store I chose. As for GPU, I won't need it because I'm not a gamer, I will use instead Intel HD 4000, which i3-3225 has.
 


Please link to the store you're going to buy from as that will help to suggest parts.
