Also, the airflow in micro ATX cases isn’t good, and there might be a rise in the temperature of the components if you use your computer for an extensive period.

Maximum medium to high-end graphics cards adopt two expansion slots each and may lengthen till 31 centimeters lengthy. Leading mid-tower cases can support two such graphics cards, filling sufficient gaming muscle for a minimum of 95 percent of gamers out there. A few gaming mid-tower cases can even adopt up to three graphics cards.

However, an entire tower case for a triple GPU setup is recommended. Also, it isn’t only about stuffing large graphics cards into a computer case. Graphic cards are the warmest components in a computer, striking temperatures till 90 degrees Celsius under load.

Toss in a 60-70 degrees Celsius CPU, and you can end up with something capable of boiling eggs. A mid-tower case’s big inner part lets for better airflow. In addition, it provides you with additional space for extra case fans and more oversized heat sinks.
