Yeah, perhaps I should have done the math in my original post.
Depending on the scenario the payback can be a _lot_ faster.  Here's a
sample:

Typical desktop PC power consumption: 100 W
Fanless thin client (Intel D410PT) power consumption: 24 W
Cost of thin client: $143*
Cost of electricity: $0.11/kWh (conveniently this works out to $1 per
watt per year so you can impress people by doing the math in your head!)
Cost of electricity per year (24/7) for desktop PC: $100
Cost of electricity per year (24/7) for thin client: $24
Electricity saving per year (24/7) per thin client: $76

Client payback time on electricity savings: 1.9 years

...and that doesn't include the HVAC savings etc.

With numbers like that (not to mention the "green" reasons) there is
really no business case for using/re-using fat desktops as clients.

* Here's the parts for the thin client ($19+$54+$70 = $143):
