So even with seriously annoying cooling (another reason to ditch the 15K drives) and relatively cool day, the CPU ran up from 29C->43C, but the HDDs barely change with extra I/O. If I throw something bigger at it, like transcoding streaming media to my PS3, the CPU will easily hit 70C...hence the reason I don't do it much. I'm interested in seeing how much (if any) power consumption drops (and corresponding heat) with under-clocking on consumer-grade kit. I haven't seen an quantitative studies on the subject so I want to do the experiment myself :) Every pushes for bigger/faster/more...I'm curious about taking big/fast/more and putting the skids on it. Thanks for the input.

I was there for that discussion. That does not cover what is in my opinion spam. Facebook and linkedin have their place but not in the context of this list.
