Server Rack (42U Standard)
The steel skeleton of the internet/Computing
A standard 42U server rack stands about 2 meters tall and can hold up to 42 rack-mounted servers. A fully loaded rack can weigh over a ton, consume 20 kilowatts of power, and generate enough heat to warm a small apartment. Data centers contain thousands of these, stacked in rows like the library stacks of the digital age.
