I want to build a really powerful gaming machine with some kind of a media server streaming full HD contents to the whole room and TV, but at the same time, a "magical button" which turns this power hungry machine into a really low power consuming web, download,.. server.
I mean, is it generally possible with the present Hardware to switch to an extreme economical modes ? I am talking about CPU, graphic card etc.. The switch could be from 400 W to 30 W or somehing about these values. Of course, in the second low power mode, I do now want any performance. Try to turn off everything what is not needed for a basic network functionality and HDD. I would say, that the button should transform this pc into a very quiet, slow pc. Or, if possible, after a period of time, automatically switch into this mode.
I am asking because I was using an asus rt n16 router with DD WRT on it router for this low power purpose, but... 1 PC is 1 PC. And it wasn't really stable by streaming etc.
