I am going to upgrade my graphics card but I might have an issue with the card fitting into the case. My case is an HP Desktop case. I know that the length will be okay, but I don't know if the DVI and other connectors will come out the back. Basically if I got a card like this with parallel DVI connectors, would it come out the back of case like this? Would vertical connectors like the ones on this card even fit?
Both of those cards will fit that case. Vertical or horizontal doesn't matter. Pcie slots are standardized sized so any pcie card fits through the slots, especially since hp uses atx cases that allow dual slot cards.
