垂直画幅4:5写实产品摄影，纯白无缝背景，一块绿色计算机主板以对角线方向略微俯视摆放并占满画面。左上方是黑色方形CPU散热风扇，中央圆形扇叶，轴心贴有紫色环形标签，下方可见黑色散热鳍片；右上方有两根纵向黑色内存插槽和卡扣。绿色PCB板面布满细密金色走线、焊点、电阻、黑色方形集成电路、银色与黑色圆柱电容，芯片和板面可见少量白色印刷字符；右下方有黑色长条扩展插槽，底边排列黑色针脚连接器。均匀柔和棚拍光线，轻微阴影，高细节，真实工业质感，无人物，不添加额外标题或水印。

Vertical 4:5 realistic product photography on a seamless pure white background, featuring a green computer motherboard placed diagonally and viewed from a slight top-down angle, filling the frame. In the upper left is a black square CPU cooling fan with circular blades and a purple ring-shaped sticker at the hub, with black heatsink fins below; in the upper right are two vertical black RAM slots with clips. The green PCB is covered with fine gold traces, solder joints, resistors, black square integrated circuits, silver and black cylindrical capacitors, and small white printed markings on the chips and board. A long black expansion slot sits at the lower right, with black pin connectors along the bottom edge. Soft even studio lighting, subtle shadows, high detail, realistic industrial texture, no people, no additional titles or watermarks.
