Stop the Noise; a couple of years ago it was just a dream but Nexus has taken that dream and made it a way of life, something we can all be thankful for.
The Nexus XiR-3500 is a great performer for both main system or HTPC computing. If you want near identical performance and would like to save a couple of dollars, the aluminum version is a cheaper option. Aside from the visual appeal of the copper fins, they perform close to each other.
Speaking of price, at 69.99 U.S. Dollars the XiR-3500 is up where just a few outside of the enthusiast crowd go. The XiR-2300 offers a better bang for the buck, but then again, if you are going to spend sixty you might as well spend seventy and not have that nagging 'what-if' in the back of your mind all of the time.
