Your gaming PC is going to be terribly inefficient and draw 10x as much power at idle as a workstation PC.
Is this really true? Modern components have fairly robust power saving capabilities. Just because it’s got a 750W power supply doesn’t mean it’s drawing 750W all the time.
A slightly related, but true, biology fact is that all mammals (with the exception of sloths and manatees) have seven neck vertebrae. So, humans and giraffes actually have the same number of bones in their necks.
