NAS Software FYI

After play around with a few Windows and NAS software including FreeNAS 8 I have come to the conclusion that Openmediavault is the best, if your using freeNAS you will see the similarities but after trying to install freenas on a dell T300 and it not booting from USB at all Openmediavault was less hassle and again its free.

If your after a free NAS Software I recommend Openmediavault
