dale, fanless is easy, just use an aluminium bottom plate and mount the CPU so it faces that way and use that as a heat sink. It will suffice if the need is there. At the same time they can also use a socketless design to save a few more $$, as if they are going this far they will go the rest of the way to save the $$. If they are indeed moving towards a closed box that will never be opened for the life of the box, that is the way to go. They can also put the AC power supply in a small external AC adaptor that will give both 12V and the CPU voltage. That would take another heat source out of the box and as long as the total system power is under 40-50 watts is very doable. These small external power supplies crop up on laptops all the time and easily run 50 watt laptops, these power supplies are also 93% or higher in efficiency so they do not heat much either.. I would expcet such a design to be quite doable with a power use well under 30 watts with 20 for the hard drive and DVD/CD. Xbox of tomorrow...anyone. One of the problems on the X-box is the cost associated with the power supply for the P-3 in it. Since MSFT loses a few bucks on each one they will want to cut those losses. Cost cutting is a game of incremental gains. An aluminium bottom plate would add little to the cost Interesting to see if AMD can muster a challenger with their new acquisition? Not this year though, but next year sometime is possible. Bill

"But suppose it launches a fanless desktop revolution?" Such could happen now, but so far it doesn't seem to be a big thing outside of Japan. With currently available parts, you could build up a fanless desktop with nForce chipset (which I have been told by a nVidia rep. supports PowerNow!) and mobile Duron or A4. Throw in a 2.5" or 1.8" hard drive and an external, brick-type power supply and you would have a very quiet, low power system. Yeah, it would be somewhat more expensive than an equivalent desktop unit, but it wouldn't be all that much more expensive. With something like PowerNow!, power consumption of the CPU is a non-issue.
