I'm putting together a file server for home use. Main uses are streaming media and storing large files that I use when video editing for a hobby/small side job.
I already have the hard drives (Five 2tb wd green eads drives), and the PSU (500w 80 plus cert). I plan to get this Areca card [newegg.com] and run the drvies in Raid-5.
So, now all that's left to buy are the CPU, mobo, and ram. I'm not really sure where to go here. I don't want to spend a bundle on it since I won't really be using the processing power of the CPU much (hardware raid), but I'd like something that's good on not using too much power and also works with a motherboard that will work with that Areca card and has onboard video/sound/gigabit.
So, should I just pick up a cheapy C2D or are there more power efficient options now with plenty of processing power for what I need? Should I use ECC memory?

Obviously, the second combo with the Sempron uses less power and is cheaper ($110 vs. $160). The question is, will it be powerful enough for what I'm doing (should be, but wanted to make sure) and will the micro atx board even fit in the full atx Antec 1200 case? Also, will the power/noise savings be noticeable or negligible, since the price difference isn't a big deal?
Also, if anyone has other suggestions besides these two combos, I am open to them as well.
