A fileserver needs to go to a home office.
The current hardware is an approx 5yr old PC with HighPoint RocketRaid 2340 RAID Card 16 ports) and it used as a fileserver. Current OS is FreeNAS, but due to driver conflicts we might need to move to another OS. As mentioned mainly fileserver ftp etc capabilities are needed, no domain, active directories etc.
I have no experience to administrate linux boxes, so the alternative would be a windows machine. Is there a reason why I shouldn't use up an old vista ultimate license that I've got in a draw? I know that it's not the "server" OS, nor is it light on the HW (such as win7)? Should I go for Server 2003 or 2008 instead and if yes then why?
Any advice and discussion very welcome
