That case has max GPU dimensions max length 13", max height 5.88". That's the original PCI standard length so there is no video card or any PCI/PCIe card longer than 13". Among the current video cards I believe the Asus GTX 980 Ti STRIX is the longest and even that's only 12" long and 5.5" high. Most video cards are 10.5" or less, even the TITAN X and most 980 Ti cards are only 10.5". You will have other problems: the 980 Ti has a 250W TDP and you probably need a liquid cooler in a case this small. (A few years back Asus had an even bigger card, the MARS II but even that would've fit if only for the length -- the reason it wouldn't fit is because it had a three slot cooling system! For very good reasons, it had 365W TDP.)
