Short answer: Yes.

Long answer:
Gigabyte GPU is 224mm long while Zalman case supports GPUs up to 360mm,
GPU specs: https://www.gigabyte.com/Graphics-Card/GV-N1660OC-6GD#kf
case specs: http://www.zalman.com/contents/products/view.html?no=19

Note: the GPU you linked has serial number of GV-N1660OC-6GD and that is 2x fan GPU (specs link above). The image at that store is from 3x fan GPU with different part number: GV-N1660GAMING OC-6GD,
specs: https://www.gigabyte.com/Graphics-Card/GV-N1660GAMING-OC-6GD#kf

So, before you buy, contact the store and ask if they sell the GV-N1660OC-6GD (2x fan) or GV-N1660GAMING OC-6GD (3x fan). Since what i see here is attempt to cheat the customer by providing false images of the product.
Both GPUs do fit the Zalman case though.
