    Are you asking if it will physically fit in your systems or if the system will run it? As for the physical side, yes it will, I believe that is a Carbide series case and should be large enough. As for running it, not sure if the power supply is up to the task. I know that some state a power supply of 550w minimum like http://www.newegg.com/Product/Product.aspx?Item=N82E16814125685 , but I tend to go over to make sure as I do not want anything to not get the power it requires. I don't think I have ever built a system with less than a 750w power supply and my next one I am thinking about twin 650-750w as I will be running two GPU's plus several water pumps and probably around 15-20 fans in stacked Thermaltake Core-X9's. Right now I have an old GTX 770 4GB running off a Carsair 1000w. Not to mention the fans and HD's all tucked in a Cooler Master Haf 922.

    Good comments by redmachine72. Power is an issue. Go with 750W. I would add that my GTX970 is doing fine both functionally and thermally without special cooling. IRay gets it up to about 65 degrees. Well within parameters.I don't overclock. The Iray documentation recommends against. DS 4.9 seems to be WAY more stable for Iray renders.

    My bigger scenes are memory hungry. My 970 has 4GB. Iray asks for 8GB on the first request. Ouch. Iray then sends smaller requests until it fits. If you can afford more memory on the card, go for it.

    Also, if your GTX is handling your screens, then you will lose memory to those processes as well. So it depends on how you set up your rig. If you can use the MOBO video to run the screens and dedicate the GTX to rendering, then that should also help.
