We have recently completed a server replacement for one of our customers.  The unusual thing is though, they now don't have a server!  We migrated their ageing Exchange 2003 setup to Microsoft Office 365 and we moved all of their data to a Synology NAS drive.  This setup cost about 10% of what the server would have been to replace, it's far easier to administer, takes up for less room and even consumes less power!  All in a weekends work for us.  If you are thinking that your existing setup needs a refresh, why not see if we can help?
