A couple of the netbook manufacturers (notably the HP mini) have used a Broadcom crystalHD decoder board in a mini-PCIE socket to allow low performance Atom + 945GSE machines to decode HD video. There's currently a fair bit of development underway to get myth and XBMC to use this hardware decoder, m...

I can vouch for an atom/ion solution.

The SPI220LE is about as efficient as you'll get without going to a picoPSU. at the 40W point, according to the review, it's 80.5% efficient, compared to 83.6% for the picoPSU, so I'd expect only a watt or two drop at idle by changing to the picoPSU. A similar drop could be had by swapping to a 2.5"...

I went with a 500GB 2.5" drive for my HTPC. It's really quiet, compared to all the 3.5" drives I've used, and uses about 1/4 the power. They're slower, sure, but you don't need a terribly fast drive for video. The only reason I can see for using 3.5" drives is cost. They're about half the cost for a...

I've verified that my Australian kill-o-watt is very inaccurate when measuring standby power. It appears that it doesn't work properly when the power factor is lots less than 1.

It would appear that the SPI220LE shutdown power consumption is a lot lower than my original measurement of 15W. I had a look at the voltage and current waveforms using an oscilloscope, and the power factor is extremely low - perhaps 0.1-0.2. http://farm4.static.flickr.com/3182/2637197368_e36a4f02c6...

I'm starting to doubt the accuracy of my kill-o-watt too. The current draw from a switch-mode power supply isn't constant.

Something is wrong here. There is no way your PC should be using 30W when off. Anything higher than 5W is extremely abnormal. Did you measure this with all peripherals disconnected?
