Hi,
I think the system is enough for a basic NFS.
The CPU support x64 and 8Gib memory is enough. The graph card is ATI Radeon
HD3200 seems support UVD hardware decode for 1080p h264 video, a little poor
for a media system.

But the cpu power is 125W, will cost much electricity for a 24h home 
system.
Using a raspberry-pi may save power, but come with poor performance, 
also it is
said that the new raspberry-pi-4 has a decent performance.

If you want to get a good NFS, please pay high attention to the power 
supply, it is
very important for hard disks. Power fluctuation may destroy your disk. 
That is
also raspberry's weakness, it generally can't provide a stable power for 
the disks.

I am not very familiar with LVM, let other people answer the question. 
But I also
recommend that you can have a look about "btrfs" and "zfs".

Best regards.
