Will a video card in my slimline?

I have a 531s slimline Dell and I'm wondering if a card like a nvidia 9800 would fit or if I would have to purchase a new case|||In a word No. but in a slightly longer couple of words, what are the specs of your machine?

I dont think that it will fit your case, but the main problem is that if yours is similar to this one:

then there is no way that your computer will be able to handle the card anyway, since the card needs atleast a 500Watt (pref. higher), power supply.
