While the front face of the desktop gets your attention, the left side of the desktop retains it. We have a transparent glass window on the left through which you can have a look at the internals of the desktop. You can customize the look of your desktop by changing the colors inside. 

The cooling system is one of the most important parts of any gaming PC. Here we have a liquid cooling system that is set to cool the processor and the GPU. You also have fans that blow the hot air out of the desktop. There are vents all over the place to facilitate the outflow of hot air.

The keyboard we have here is a mechanical keyboard and is a pleasure to type on. The keyboard comes with a dedicated number pad which is a nice thing to have. The keys have excellent key travel and you can type on it for hours without feeling any pain in your fingers. 

There are four RGB zones on the keyboard that can be customized to your needs. The palm rest is bigger than usual and gives you all the space to have a comfortable typing experience. You can also find extra buttons that’ll come in handy as well. The gaming mouse we get is nice and is more than enough for your gaming needs.
