The first thing to bear in mind is that Exchange 2007, the latest version of Exchange, will only be supported on 64-bit servers.  Initially this may sound like an odd decision by Microsoft but they claim that almost all new server hardware these days has 64-bit technology anyway which means that new installations will be able to utilise better sizing and scalability options.  If you refer to Microsoft’s documentation, it clearly states that in order to run Exchange 2007 you’ll need x64 architecture with either an Intel Extended Memory 64 Technology (Intel EM64T) processor or an AMD processor that support the AMD64 platform.  The Intel Itanium family IA64 processors are not supported.

You’ll also need a minimum of 1GB RAM although 2GB is recommended and at least 1.2GB of hard disc space, which must be formatted as NTFS.

To check if your processor is compatible, you can use CPU-Z which is available here.
