Any real data for these claims? Nick has posted measurements on this list many times.

The calculations pretty much added up for me with domestic electricity prices in Finland and no cooling costs (it's cold enough here anyway most of the time). Caveat: an inefficient PSU may be worth replacing with an efficient one. Maybe. This is assuming 5 years service life, which is not very hard to get with carefully chosen hardware from the dumpster, but seems to be too much to ask when buying new... Saving 10 watts will save you (0.01kW * 24h * 365) = 87.6kWh per year. Realistic savings might be around 20 watts, for a 35-40 watt P3 and 15-20W Atom. Calculate for yourself if it is worth it. Small-ish, dull looking HP, IBM, Dell and other "name-brand" office PCs tend to be rather low-power, and quiet too. It takes some time to learn to dumpster-dive the correct machines, after that you will be able to find them easily. > why pay 100dollars/month, 1200dollars/yaer for a server ???. 2 plateform > Atom = 120 dollars, 1 firewall, 1 serveur web, 1 disc openbsd4.7 = 50 > dollars :).

Since when have recycled machines cost 100 dollars a month?
