All worked first hand as expected. I am using this for a media centre type of computer. I installed a Core 2 Duo E8600 CPU trying to minimise energy avoiding to lose performance, some silent fans, resulting in a very low noise box suitable for the living room (under TV).
I am running Kubuntu 8.04 (Hardy Heron) with KDE 4.1 and all the mythtv goodies and two tv cards. The machine is very stable, running 24 hrs, recording and playing flawlessly. Also used it to watch DVDs, streaming music to my Sounbridge, etc.
I was worried that the chipset was not supported by the Linux kernel, but those kernels guys sorted out quickly. I had nothing special to do. The nvidia video driver was also automatically detected and setup. Not a complain with it. CPU temperature is always under 40 degrees. I am very happy with this purchase, and I am trying to make the most of it. Excellent price.
