Is this case big enough?

I want to know if the Fractal Design Core 1000 is big enough to hold the Xigmatek Gaia SD1283.

Also will the Core 1000 limit the airflow I get from the Gaia?

It looks like it will fit comfortably, it is a very small heatsink. Fractal are known for having pretty good airflow.
