I don't want to start a fight with Gary, but my PRS runs on a Dell without any problems.

I bought it new 2 years ago. It was the cheapest Dell desktop offered by Best Buy at the time. My Comm speed is over 75 and I haven't installed any special port cards, etc.

I may just be lucky with my situation, so I would follow all the advice offered above... Just thought that I should add my experience to the general pool of knowledge.
