FX 4.5L is the most compact and lightweight Aluminum case with an internal Power Supply. In this case, you can assemble a medium-powered computer for work and play. For example, it can be an assembly on a mini ITX motherboard with core i7 processors and an RTX 3060 or RTX 2070 video card.
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.
The range also includes the FX lm 4.7L model and the cheaper FX stl 4.7L steel model. They are slightly wider and allow for coolers to cool the CPU down to 47mm.
