this case is the same that is used in HP consumer line PC's there are no extra random case parts in the way of a video card. there are 2 things you need to do with your video card.
1.) buy one with out a full length heatsink. the full length heatsink will cover your top 2 SATA ports.
2.) buy one with pci-E power connectors on the top, not the back.
aside from that you should be fine. the case is BTX so the video card back will be against the ram slots while the top will be almost touching the card reader bay.
if you can find a single wide card i would buy that but a dual wide with only a heatsink and fan should fit just fine.
I have used tin snips and a dremmel on these types of cases before to remove the memory card reader...
