We need a 64 bit platform/proc. for this OS and am thinking of buying a HP PC from DABS which has a 64bit processor (HP PRO 3015 MT Athlon 2 x2 215 2GB 320GB Windows 7 Professional) and just overwrite the OS on there to run SBS. We could add more memory (say 4Gb) and another hard drive for files/backups. So with around £400 we have a server! Are we thinking on the right lines here?
