However, when you open the unit, there is a lot to see in there, besides, you can’t fill the system without opening it anyway. So, we removed the top lid using the included hexagon wrench:

We discovered that there is an aluminum tank with acrylic side panels right in the middle of the unit:

There are three pipes coming out of the tank, two of which are leading directly to the unit side panels pierced with aluminum pipes:

So, as we have assumed, the side panels of the main unit function as a radiator for the entire liquid-cooling system. There are two small pumps built into acrylic side panels of the aluminum expansion tank. Unfortunately, we don’t know anything about their claimed official performance, because there is no mention of them in the technical specification sheet. There are two thick foam pads stuck to them to reduce the noise from working pumps:

Moreover, the bottom of the unit as well as the top lid are also covered with foam padding. That is pretty much it concerning the main unit. Now let’s discuss the CPU water block.
