Recommendations for an Linux/XFS based NFS file server?

[James Pearson <james-p@xxxxxxxxxxxxxxxxxx>]

I'm thinking of setting up a Linux (i386) based NFS server with approx
1TB XFS file system (on an external FC RAID box).

What hardware would people recommend for this i.e. make and type of
mainboard, fibre channel card, gigabit card etc. What are others using
for this purpose?

Thanks
