My cpu casing is a dell vostro 260 mini tower.
Can a gtx 680 fit in it?

Open the case to make the measurement like in the link http://cdn.overclock.net/e/ee/500x1000px-LL-ee575342_P1010034.jpeg then you will know the gtx 680 will fit or not. You can find the gtx 680 dimensions from the manufacturer website. Also you need the good at least 550W PSU with 2X 6pin for the gtx680.
