This will be my first build so I am looking for any input on gaps in my plan or pitfalls to watch out for.

My primary goal is low power consumption because this system will be running 24/7. I am looking at running Ubuntu, MythTV (backend). I plan to use an internal USB Flash drive as the boot disk and get video content from an HD Home Run and the Internet (trying to cut the cable).

My main concerns are:
1) The ability of the Core i3 to handle video transcoding to support capturing 2 video streams while watching a third stream in real time. This would my concept of a peak load.

2) The amount of RAM. Is 8GB overkill or not enough? Would 4GB be sufficient or would it degrade streaming performance? Does more RAM increase idle power consumption?
