I downloaded and installed SUSE Pro 9.1 last night, smallish (28MB) installer than goes and gets around 1.2Gb of data from an FTP site.
What a pleasure it is. The install was very easy, kept me informed what was happening all the way through.
Everything about SUSE appear to be incredibly logical so you don't feel uncomfortable with anything.
I've configure Samba and it's fully visible on my network, I just need to work out how to set up local network "public" access to drirectories on the data drives.
Adding extra HDDs is also very simple. just add the disk and YaST finds it and gives you a very easy interface to tell it what you want it to do.
I'm currently going to take some advice I've read here and elsewhere and format them as unix partitions rather than using NTFS.
This has so far been a very positive experience
Mark.
