Buying Tips For The Smallest ATX Cases
Even though it is a small form factor ATX case, it will accommodate normal ATX components. When buying compact cases, you should focus on the following:
Components Of The Build – If you already have the main components of your build, you should choose a case with ample space for them. Not a snug fit that will make the experience difficult. Examine the CPU height, GPU length, and power supply length.
Case Build-Quality – Do not be fooled by attractive cases made with inferior materials. All-steel or aluminum cases provide the most durable chassis.
Expandability – Consider how simple it will be to expand your system in the future. More drive bays and PCIe slots mean that you may add more components to improve the system’s performance.
AirFlow – Besides selecting a case with a spacious layout, pay attention to the cooling options. Most compact ATX cases have fan/radiator positions that are poorly engineered. There are some with less than two 120mm fan options. Ensure that your ideal case has the best airflow to keep your system running cool.
Cable Management – Consider cable management with airflow and interior space. Choose options with cable routing channels and cut-out areas.
