My main concerns are cooling and fitting the video card, and the motherboard working with the case while having most/all of the input/output ports available. Also I am putting strong consideration in getting an SSD boot drive, so having a case that will support one with minimal hassle is also to be taken into consideration.
Lian Li is almost in a class of its own. It's expensive, because it has exceptional build quality. Value-for-money though, I'd also take the CM 690II or the CM 690II Plus. Excellent cases, well built and fairly well-priced for what you get.
According to the HIS website that card is 26cm long.
The Storm Enforcer can take cards up to 27cm without removing the removable HDD cage.
The K7B can take cards up to 28cm.
The figure I have for the CM 690 II Advanced is 30cm, but I don't know if that is with or without the HDD cage removed.
