Is there any software out there that gives openSuSE some sort of gui (web or x-window related) to manage tools that give the user a NAS like usability.

I currently do use my suse 10.3 box as a NAS, but it gets a little cumbersome sometimes keeping track of all the users, samba shares, NFS exports...
Yast is partly there but I'm looking for something with the ease of use of something like FreeNAS or OpenFiler...

Any ideas?
