1. Please provide a link to the exact Corsair Dominator GT memory modules you want to purchase. We need to look at the specs and images in order to determine if the memory module will interfere with a tower style cpu heatsink.
2. Please provide a link to the exact pc case you intend to use. We need to check the width of the case in order to determine if the case is wide enough to accomodate a tower style cpu heatsink.
Here is a link to a very good web site with a lot of useful information about cpu heatsinks that will help you make an informed decision:
The memory modules will have to be installed without the tall, comb like, heatspreaders. A memory module with a tall heatspreader located in the memory slot closest to the cpu socket will interefere with large tower style heatsinks. Tom's Hardware has published several memory articles. The articles mentioned that tall heatspreaders are a waste of time. Other sites have confirmed the findings. Optimal meamory cooling is achieved with no heatspreaders. The cpu heatsink fan is so close to the memory that it pulls air right over the memory modules.
The Jeantech Unicorn case is 235mm wide. That works out to 9.17 which is much wider than a typical case. The case can easily accomodate any of those extra large, 160mm tall cpu heatsinks and still have room left over for a fan on the case side panel.
I took a look at images of the motherboard. I did not see anything that would intefere with a cpu heatsink.
