I own a Mini tower. It is Acer, Vista, Aspire X3810. I also recently bought Diablo III but I didn't have a good enough video card. I need atleast a NVIDIA GeForce 7800 GT or ATI Radeon X1950 Pro or better.. Well I didn't realize that the Mini Towers don't have enough room for those big of Video Cards. Please, What video cards will fit this type of tower that are as good or better than the one's I mention!?
