As my understanding from custom loop, you have to fill the reservoir and keep the pump cycling until the loop is full. With the built in reservoir and being painted black from the pictures, how can you tell if its full?
Refilling can be done inside or outside the case. When possible we recommend to do it outside with your power supply only connected to the kit and nothing else. Assuming you've already added your GPU and that tubes and clamps have been reinstalled, all you need to do is: have the radiator sit flat on a table with the tubes facing down so that the block/pump is effectively lower than the radiator. Open up the cap and start pouring liquid. At this point the pump is still off. Keep adding liquid until the radiator is about full. Lift up the reservoir side of the radiator with the other side still on the table so that the liquid flows down the tubes, you will hear some gurgling as the air inside the tubes goes back in the radiator. Repeats this until you can can't any more liquid. Start the pump with your power supply - you should see water moving slightly in the reservoir showing that fluid is being pushed. Keep the pump running until all the air is bled, this may take up to 30 minutes, you will need to keep adding liquid. When you can't add more, close up the reservoir cap and inspect the kit and finally turn off the pump. Install it back in the case, voila.
