TL;DR
It is shown that despite the high energy cost associated with computer manufacturing, the typical desktop computer is used only a fraction of its expected time, which could amortize the energy required to build a computer.
Abstract
This paper discusses energy consumed by a typical desktop computer. We show that despite the high energy cost associated with computer manufacturing, the typical desktop computer is used only a fraction of its expected time. Increasing PC lifetime by reuse could amortize the energy required to build a computer.

Energy Use and Power Levels in New Monitors and Personal Computers
57 Citations2002Judy A. Roberson, Gregory Homan +6 more
A trend among monitor manufacturers to provide a single very low low-power level, well below the current ENERGY STAR criteria for sleep power consumption means that energy consumed when monitors are off or in active use has become more important in terms of contribution to the overall unit energy consumption (UEC).
