I'm considering an upgrade to my HTPC with a new CPU, mobo, and RAM. My current machine runs an Athlon X2 4850e (full specs in sig) and I'm not unhappy with its performance, but I want a newer mobo that can POST faster, and DDR3 support so I can upgrade to 4GB RAM.
This will be used entirely for media, streaming, and network storage so I am not looking for any kind of powerhouse. I'd also like less power consumption than what I have now—ideally under 30W idle. Price and power consumption are the main considerations. I will be undervolting and possibly underclocking it. The main option I'm looking at right now is an Intel G620 with H67 mobo. I was hoping to get some input from someone more familiar with building a low-power machine.
