Recommendations

For optimal airflow, install intake fans behind the vented front panel and exhaust fans at the top or rear. If using a long graphics card, confirm GPU length compatibility with the 420 mm maximum and plan cable routing using the case’s cable management features. Download any necessary drivers from the manufacturer’s website to enable front-panel display or additional control functions.
