SG04-F improves every aspect of the former case from specification to user impression. With additional expansion slots and reversible power supply unit installation design, SG04-F owns a superior cooling performance which can support operating dual graphic card (10.5 inch) within it. Adjustable fan positions enable users to devise their own cooling layout as required with the front door helping to reduce noise effectively. Packing with thoughtful features, the SG04-F is truly worthy of living up to become another benchmark SFF enclosure.
