Best Open Air PC Cases in 2021

Open air cases are not exactly a new thing, they had been around for almost a decade or so, they somehow started in the modding era but I've been seen a lot of these lately.
The biggest advantage of these cases is the unlimited ventilation due to the fact there isn't any blocker or panel around it that stops it from receiving air.
But the lack of panels becomes a disadvantage because the air carries dust which is going to head directly to your components, and the noise is going to be louder than your regular case since this is not bouncing any panels inside a case.
On the other hand, these "cases" look amazing. So clean, elegant, minimalistic, and they need less space in your desk than regular ones.
