FX lm 4.7L is the most compact and lightweight aluminum case with an internal Power Supply. It was designed for high-end components such as Core i7 processors and GeForce RTX2070 graphics cards.
The arrangement of the components according to the "Sandwich" type allows for good cooling. In this way, overheating of the components can be avoided even without additional blowing from the case fans.
There are also more durable FX stl 4.7L cases in the range. They are slightly heavier than aluminum ones but are cheaper.
In the meantime, there is no need to worry about it. ”
