Here is a one-paragraph noir scene set in a data center:

The fluorescent lights cast an eerie glow over the rows of humming servers, their blinking lights like the eyes of a thousand silent witnesses. I stepped between the racks, my footsteps echoing in the cavernous space as I made my way deeper into the heart of the data center. The air was cool and dry, the scent of ozone and burning electronics hanging thick. I knew my target was here somewhere, hiding among the digital ghosts and shadows. This was his territory, his domain, but I was a shadow myself - a ghost in the machine, hunting the hunter. The only sound was the steady thrum of the cooling fans, a heartbeat that seemed to grow louder with each step I took, as if the very data center itself was daring me to come closer, to uncover its secrets. But I wasn't about to be deterred. This was where the trail ended, and I was going to find him - no matter what it took.
