Yeah, except that the cost of power to run those machines can be significant. The most obvious difference would be reducing consumption by replacing a CRT monitor with an LCD. That should have minor effect on Ubuntu ... today ... maybe. But I do remember fighting to get a monitor configured a couple of years ago (before I moved to a Mac).
Are modern desktops more efficient than 10 years ago? Hard for me to say although Intel has a paper that says that Energy Star and other measures make a big difference.
Probably the easiest thing to do would be to swap the old desktop for a modern laptop. You'd gain all kinds of energy savings - LCD screen, automatic sleeping, etc.
