How to find the best computer case in 2021? Well, you have to take into consideration certain factors that contribute to the normal functionality of the computer. You should also check for removable back expansion slot covers, made of durable materials. If the covers break off then the airflow will suffer and compromise the fans functions. Another important thing is the presence of rubber grommets for proper screws. If the components vibrate, make sure that the vibrations won’t affect the screws stability. Make sure you find a case with solid rubber grommets safely tucked away between the screw and case, which can absorb the vibrations.

It is important to find the best computer case in 2021 and safely invest in the computer’s performance. The case should include different fans for proper air circulation. With the right fan coordination the computer case will maintain the interior components properly cooled. There are also nontechnical features that add styling to your computer. Why shouldn’t you keep your PC beautiful and with a touch of elegance? Well, you could also add special lighting effects in the case for an elegant aspect. The light illumination surrounding the case can add a blue and red effect ideal for night ambiance. Furthermore the case should also come with dull edges inside the case. Avoid opting for sharp edges that might harm you.

Antec Nine Hundred Case


2This computer case is best for gaming. Gaming emits loss of heat due to intense CPU working. This case has 200 mm top mounted fan that cools the whole CPU. To provide additional support to the top mounted fan, it also has two 120mm TriCool blue LED fans at front that helps to cool the hard disk. Even if they are not sufficient to cool the system down, it also has Optional middle 120mm fan bracket. It can support up to 6 hard drives. Its design and functioning makes it my favorite computer case.



This is, according to several gamers, the best computer case under $100. It is incredible when it comes to cooling down the most demanding gaming systems which is pretty much all you want from a computer case.

It comes with a perforated front bezel which allows airflow. This way it will cool each and every one of the six HDDs it allows you to install.

The three fans are very quiet and will probably be overwhelmed by other sounds coming from the main unit.

It can incorporate a cooling system which works on water.



The power supply mounts at the bottom which means you will have to get longer cables.

The earphone and mic jack are placed in the front of the case which may not be supported by a series of motherboards.

Cable management is poor.

There is not much room for improvement with this case which is a bit of a letdown if you plan on constantly investing in new hardware.
