Whether the OEM packaged processors have a 3yr warranty like the Boxed package?...And in the Boxed processor package is the heatsink already attached to processor? If it is can it be seperated easily? I'm building an SFF in a Shuttle XPC box. It has its own ICE Cooling heatsink so I only need the processor. But if the OEM package is without a 3yr warranty I think for an extra $10 I will get the Boxed package with its warranty. Thanks for any input.
