Can anyone recommend some components for building a completely silent pc for the bedroom that I can use as an HTPC? I'm realy pleased with the way I can provide the same experience on all the machines in my house with mediaportal (unlike previous attempts with Vista+xbox360), and so now I'm thinking of building a silent pc for the bedroom. I'd appreciate people's suggestions for components. Size isn't really an issue, I can hide the box away easily enuf.. I just want it to be completely silent (fanless?) and hopefully not too expensive..
