The case was definitely a bad choice when i didn't realize that non of the dual Fan or Long radiator Water Coolers won't Fit but LUCKILY I was able to manage to install the H100i GTX after a few search on how to.
There's a risk of getting your Radiator scratch when trying to install it. And yes it was a bit of pain in the butt when i was trying to fit it in. I had to use the Vent holes to screw it up and it literally have to be near the side panel.
And hey it really works pretty well for me. I have never had a problem installing the rest of the parts. it's just that the Case is way too small for a longer radiator.
