An ultra-realistic, hyper-detailed HD image of a traditional Nativity scene (complete with Mary, Joseph, baby Jesus in a manger, shepherds, and animals like sheep and donkeys) set inside the open casing of a computer CPU. The scene is scaled to fit perfectly within the intricate interior of the CPU, surrounded by components like the motherboard, wires, cooling fans, and microchips. The Nativity figures are carefully arranged as though they belong in this setting, with glowing LED lights from the CPU adding a modern, ethereal touch. The overall composition should blend the rustic feel of the Nativity with the futuristic, high-tech environment of the computer. Ultra-detailed textures for the components and figures, with lifelike lighting and shadows for a striking visual effect
