Best Open Air PC Case for Enthusiast Gaming Build in 2018

If you are an enthusiast and looking to build a stunning looking PC using an Open Air PC case then you are right place. Open PC case gives you the complete view of all the components installed in your PC, and you will be able to show all of your high-end components installed in the case. Open Air PC Case or Open PC Case looks more stunning and beautiful when you have fancy RGB components that include RGB CPU Cooler, RGB RAM, RGB Fans, RGB Radiators or RGB LED Strips. Some open air frame pc cases also come with tempered glass panels that further enhances the beauty and look of these computer cases.

The advantages of Open Air Computer Cases are generally associated with looks only, but test bench open PC cases allows you to easily remove and install components without having to go into much trouble. Also, open frame computer cases do have also some benefits in overall cooling performance too. This is because the open nature of these computer cases allows better airflow, ventilation and thus greater dissipation of heat to the surroundings.

The main disadvantage of Open Air PC Cases is that the dust can accumulate on the components at much faster rate compared to the closed computer cases, and small insects can also enter the case and can interfere with the components or can make a mess in the case. Also, they may be difficult to move around when all components are installed in it. So, portability is another drawback of open air PC cases. Here in this post I going to list down the best open air cases for building a high-level computer or enthusiast gaming build.
