I'm going to get a better video card, but for building this system for less then $150 that's not bad, and that was starting with no parts at all not even a case
My wee little netbook running windows 7. It's been heavily customized but unfortunately that can't overcome the anemic Atom processor (though it is running at 2ghz). The Ion GPU has a Geforce 9400 core built inside, and it handles HD video (at 1080p) with zero stuttering.
Once I have my giant hdd (750gb or bust) hdd, I'll have the ultimate mobile media machine though. The Digital/Analog TV and FM tuner really rounds out the media side of things, and the GPU makes slightly older games (Portal for example) run surprisingly well. As for my main PC...I would be amazed to see any of it hit 1.0 on the WEI
