After some research, I read that the latest Xbox 360 Arcade models have the latest Jasper based motherboards with 65nm CPU & GPU. Per my research, this new Jasper model runs cooler and in turn is more reliable. If I am not mistaken, those models with manufacturing dates of November 2008 or later & power supplies rated at 12.1A on 12 Volt lines contain Jasper motherboards. Is this correct? I have not seen any Xbox 360 Pro systems with later manufacturing dates. If this is the case, I may purchase a 360 Arcade and hard drive separately.

Anyone utilizing a 7200 RPM hard drive with the Xbox 360? If so, is there any performance difference compared to 5400 RPM?
