and for more money
m-audio drivers kick butt as well, no issue in any linux distro I've tried or in windows. and the front two channels on that 7.1 chaintech use parts that are about equal to the m-audio.
I'd recommend this PSU over the gxs one, same thing, different fan controller, I replaced the OCZ because it was always humming over quieter music. http://www.newegg.co...N82E16817104014
Lastly, I'd recommend a hitachi deskstar over the WD.. the failure rate I have seen on them for people other than me(also in addition to me) is staggering.. maxtor and WD are drives I always know to mention if someone says their drive just failed without mentioning a name.
As for the rest of the guide, it's 10x better than anything I could have ever come up with, if I could have come up with anything.. awesome job. The detail you went into is great, compared to a CNETish uninspired "buy this because we reviewed it well, we will say some feature of the product is the reason it got a 9 rating to hide the fact that we really know nothing about any of these products." The only thing I noticed left out was HDCP, which I find to be a very good thing. The less guides telling people to jump on the bandwagon with that nonsense, the less likely in ten years we'll be buying separate copies of a tv show for different TVs.
