A look Inside
To gain access to the internals the first thing you will need to do is remove the four screws at the back of the system. This will allow the motherboard tray to slide out giving you access to install the components needed to get the system operational.
With the motherboard out you can now install the CPU, RAM, and storage. Which is quick, easy, and painless.
Finally, while you can opt for custom cooling if its under 47 mm in height, ASRock does include a basic cooler, and it uses AMD's clip system making for a relatively quick and painless installation. Once that is done just slide the tray back into the chassis and your good to go.
