Because how in the hell is anybody supposed to find parts that are actually available, TO YOU, without knowing that. If you don't want to share where you are located, I'd suggest that you find a forum in your region so that you can get build suggestions that are relevant to you. It does no good to offer build suggestions for somebody in the US, or UK, or Australia, if what is available there is not available where you are, and we already know that shipping from country to country will generally add about 100% to the cost of parts, so that's senseless.
