I do love FreeNAS, at home and at the office too (for development purposes - I'd trust it for production but with our client base it's better to be more "corporate").
It has a good cross section of features from 'home' to 'pro', AFP/NFS/CIFS/iSCSI, directory integration, plugins (more aimed at home, with things like news downloaders, BT clients).
