Hi,

1) Why 32 bit, all proc's are 64bit these days. Linux doesn't suffer 
from the same issues as Windows where by you have 32 bit drivers etc. 
With everything compiled, an arch. change is pretty quick for Linux. 
Technically, as soon as gcc supports it, so will linux :)

2) I stick to ext4 generally. I have yet to see the advantage of xfs or 
brtfs or <insert_fs_here> (Keep the flames for later about why x is 
better than y :) )

3) Have you thought of putting the 2x1TB and 1x2TB into a LVM array and 
stripping the data (you can mirror *insdie* LVM, but it needs 3 drivers 
to be statefull - as in commited to disk, otherwise it re-syncs after a 
reboot) - perhaps an idea :)

Cheers,

Pieter
