The case looks like it can take standard profile cards, and looking at the positioning of the PCI-E x16 slot, you should be able to put a double slot card in there (that basically means you can put anything in there). The only thing you will need to worry about is the length of the card as that case looks quite compact, so longer cards (especially some ATI ones) may be a struggle, impossibility to fit in length ways.
The other thing you need to worry about is the PSU, chances are the PSU included will not be enough to handle modern graphics cards unless you get a really weak one that will be as useful to gaming as a chocolate teapot.
