64-bit OS on PowerEdge 2650?

Hi,

I'm not sure if this should be under servers&storage or software&OS.  I'm trying to find out if a PowerEdge 2650 can run 64-bit WS2K3 or 2K8 and, ultimately, Exchange 2K7.  I think all parts could support it, except for the processor (I'm not sure).

I know it has Intel Xeon (don't know model number, but it should be the default for the system - I don't think we've done any upgrades to the machine), 3.75 GB RAM, 33.8 GB system partition and 546 GB second partition.

Any help, suggestions or recommendations are appreciated. :emotion-1:

Thanks!
