Well apart from documentation the servers are completed. Samba now working as a PDC with roaming profiles for my wife’s XP laptop, mail server finished and working with all the Horde issues now resolved. Running on a new motherboard, so seeing more of the 4GB RAM that’s in it, and able to connect 6 SATA drives (so 8 all up).
Just have to document the mail server setup now… then post back some howtos here.
