BTW, couldn't get FlexRAID to work for some reason so I went looking for something similar:
SnapRAID - Filesystem agnostic parity based data redundancy, (Linux/Windows).
Elucidate - A GUI for SnapRAID (Windows).
Liquesce - Drive pooling for Windows.

All free.

This is the solution I came up with for my N40L HTPC, it is almost perfect apart from one major issue which I have detailed here  http://www.tuckshots.co.uk/Temp/Liquesce.htm

Have you experienced missing files in Liquesce storage pools when browsing over the network?

I have since experimented with RAR files and created a folder with 500 3GB files in.  This time I could only see 453 of the files over the network
