This was to be my point exactly ... what good does a machine that can boot up into a file server with last months data or a web server with last months data be if the current server just died? If you have a backup system in place with the ability to push certain directories onto this machine, then maybe. Otherwise, this seems fairly pointless. A live solution with Virtual Machines and something like DRBD might work ... though the machine would by fairly heavily loaded just keeping everything updated if live for 4 other machines.
