All the way on top we see a cover lid...

Exactly, here where we make a pit stop and poor in the (supplied) coolant which means this is direct access to the water reservoir. I can surely appreciate this innovative location to fill her up.

Moving slightly downwards we stumble into the front-panel. The location is really good, easy access. Below we find a water-level indicator. Good stuff as you can see how much coolant is in the circuitry.

A noteworthy detail, if your reservoir is not filled with enough coolant then an alarms will start to beep. This is an excellent safety feature preventing the water circuitry.

From left to right the power on/off, reset buttons and HD/PW LEDs (colored blue when activated). Then we can see a fan controller which regulated the RPM of the radiator fans. In the middle we can see a coolant flow indicator, if it spins .. you're good to go :)

To the right the usual connectivity which internally will need to be wired to your mainboard.
