n old PC can be set up using FreeNAS, which is a LINUX-based application

If you are using a PC as a NAS server why not just install Linux anyway? Set up NFS or SAMBA shares and Bob's yer aunty! I did not want to use a PC though anyway coz a nice little NAS drive sits on the hall table near the router with no monitor, keyboard or mouse:-)

Thanks ayway.

Cheers
