Low Power Intel 775 Chips?
 

I have an MSI board that is surplus but fairly new. I ran it with an Intel 830 CPU for Vista Beta testing last year, and am casting about for a new use. I've been mulling building a small box for Windows Home Server for a while now, but want to know:

"Are there any 775 chips that are above 2.5ghz and have speed step technology or inate low power consumption like Intel Core Dou Mobiles do?"
