Here's a noir-style paragraph set in a data center:

The server racks loomed like steel sentinels, their blinking lights casting a cold blue pulse across the empty floor. Jensen moved between them, his footsteps muted by the constant drone of cooling systems. He knew the data he was hunting was buried somewhere in these machines—encrypted fragments that could bring down an entire corporate empire. His fingers, calloused from years of coding and late-night keystrokes, traced the network cables like a safecracker feeling for tumblers. Something had been wiped, but in this digital underworld, nothing was ever truly gone. He could smell the faint ozone and stale coffee, the scent of secrets waiting to be excavated from silicon and shadow.
