First, It will most likely require a different PSU than what comes as OEM in there, in which case, you will have the connectors you need. I had a Mini Tower eMachines that I gave my Sister and I had put a 9" card in it. As I remember, I may have been able to go to 9.5", but not entirely sure as it has been quite awhile since I was in that thing. The GTX is 9.5" in length. Any standard ATX PSU will fit in the case. With Dell, they used to be propriatary and that created all sorts of problems.
