The YY-5601 comes equipped with plenty of expansion room in the form of 7 PCI/AGP slots ready for use. The tabs covering the slots can be easily removed once the motherboard has been mounted. Yeong Yang has moved away from traditional 80mm fan mounts in favour of a 120mm fan exhaust mount, which provides perfect air circulation for a case of this size. The integrated stamped grill should not impact airflow but consumers wishing to maximize air circulation can easily cut this area away with any type of rotary tool.
