I have this case and that wont fit. Max length for the video card is about 11 -11.2 inches. I forgot the exact measurement. HOWEVER, you can cut up the 2 floppy bays to make room for it.
EDIT: I just measured my the length and the card will barely fit. I have a Sapphire 7950 that is 10.63 inches long and I have 1.25 inch to spare. So you will be able to fit the card in your case. If you're going to go SLI in the future, you need to cut into the HD Bay.
Would it fit in the dark blue slot? meaning the position the dark blue slot holds the card relative to the case..
Yes, that will be just fine.
Not sure if you got an answer yet but I used to have the same case and I had two gtx 770's in sli in that same case. But you might want to consider an upgrade imo the case just really looked bland and really didn't have the best airflow even with static pressure optimized fans. just my opinion
Quite easily. I had a Challenger and it would fit cards an inch longer than that one.
