Brent look at rule # 3 on the
Forum Rules and include the all the items in 1&2. This is what cyberjock and I have requested from you.
Since you're in the process of ordering drives, it sounds like you might be jumping the bit. Have you read
cyberjock's guide? Also read up on the official
FreeNAS documentation
If you're following the Lifehacker article about turning an old pc into a NAS, while it refers to "FreeNAS", in reality, they are talking about
NAS4Free. That article says that you can use "A PC with a minimum of 192MB RAM".
That's not the case with FreeNAS, which has much higher RAM requirements. For UFS, 2Gb is probably adequate, but for ZFS, you'll need a minimum of 8Gb.
