I would tend to doubt that the processor is going to make all that much
difference on a server whose primary function is to provide NFS but my
own thinking is...

1 - I prefer good hardware RAID over software RAID.

2 - Peformance using RAID 1 or 1+0 (4 drives minimum) is much better
than RAID 5

3 - I really like having at least a mirror RAID (RAID 1) on the boot
volume as well as the data drives so in a server I wouldn't necessarily
segregate the OS from the data on physical drives but rather in
different RAID partitions.

4 - I would probably use RHEL or CentOS for this server rather than have
to deal with the churn of many upgrades using Fedora. I like Fedora for
Desktop and specialty server types but not a network backbone system.
