> I definitely value lower power usage when idle. My desktop PC uses ~150W when idle.

These two statements appear to be in conflict. 150W is a high idle power consumption for a modern PC. Unless you have something like an internal RAID or have reached for the bottom of the barrel when choosing a power supply, 40W is on the high side for idle power consumption and many exist that will actually do ~10W.

There's a couple dozen of us stuck with older hardware because we have less money to throw around.

In this context "modern PC" is pretty much anything since approximately Ivy Bridge. You can get one of those -- the entire machine -- for less than $50, and somewhat newer ones for around $100. If you're currently using something with a 150W idle power consumption on a regular basis, you're losing more than that in electricity.
