Unfortunately nowhere near my desktop right now so can't just open it up and check but want to order another 6950. Also, I have an 850 PSU, that should be able to handle the 2 6950s, an i5-760 CPU and all the small stuff, right?
More aboutwill case 6950s
Yes it should fit if your motherboard allows it
You'd be hard pressed to find a configuration that the HAF-X wouldn't fit.
