Hi, I am looking for a half-decent low-profile graphics card to use with my Dell Optiplex 990, and the Sapphire Radeon HD 7750 seems to check out nicely, but I do not know of it will fit in my system. Those that have an Optiplex 990 SFF will know that the space inside is very small and cramped, but I'm hoping that the graphics card will fit inside it. So, for anybody that has an Optiplex 990 SFF and/or a Sapphire 7750, will it fit inside the case? Thank you!
