If I were you I would goto dell.pl it is only in Polish although you can check the English version at dell.com and copy your selection into the Polish site.
I bought a Dell last year and im quite pleased with it, good prices and reliable hardware.
I think you will find that a lot of models that are available in the US will not be available in Poland, as is the case with most of the manufacturers such as dell, asus, toshiba and such like.
komputronik.pl is a site that I use for my business computers it is in Polish but they do speak English and they might help you.
