Japanese translation help.
How would you translate "pesocon no ushiro ni wa nanika arimasuka".
My translation is "what is behind your computer" but that seems like a strange question to ask.
Am I missing something
the question "anata no pesocon wa donna pesocon desuka" proceeds this one if that helps at all...

Question

Answer

It means "is there something behind (on the back of) your computer?" rather than "what is behind your computer?" 
So the person first asked you "what kind of your computer do you have?" Then (s)he followed by asking, perhaps because you weren't able to give him/her an exact answer, "is there something behind (on the back of) your computer" in order to determine what type of computer you have.
