Nice site.. but why did you bought a .net .... I think you should have bought .com domain.. Its much better...
Good layout. The colors about the best part of your site. Bu what I dnt like is that there is no perfect footer for your site. Create more space in the footer. Also write down some legal words to save yourself from Microsoft. Like Xbox360system.net is not affiliated with Microsoft. Xbox and the other brands shown here are the Trademarks of their respective owners. ...... The site is good 8.5/10 for the frontpage.
I really like it. The only thing I see wrong is that watermark xbox logo in the top-right corner. I think you should do something about the quality of that image. And yes, ditto to the footer and a disclaimer.
