NAS 風道剖視，硬碟與後風扇一眼看懂

A four-bay desktop NAS concept shown as one cutaway isometric 3D object, four drive trays in front, motherboard on the side and one large rear exhaust fan. A few translucent cool-blue airflow arrows enter the front and exit the back without obscuring parts. Pale neutral background, physically plausible spacing, no text, educational concept not measured thermal simulation. Original generic design, no real brand or fabricated specifications.

四盤位桌面NAS的單體等距3D剖檢視，前方四個盤架、側面主機板與後方一個大排風扇。少量半透明冷藍氣流箭頭從前到後，不遮零件。淺中性背景，間距可信，無字，教學概念而非實測熱模擬。 原創通用設計，不虛構真實品牌引數。
