ECC Memory Question

First, please don't bring up the ECC vs. non-ECC argument here. I do understand the risks of running non-ECC memory. In fact, that is part of the reason I'm making this post.

I am currently in the situation where I have a running FreeNAS system with non-ECC memory. I am in the position to be upgrading this system soon and I'm considering switching over to ECC memory in the upgrade. I have the money and the system has grown to the point that I no longer consider this as acceptable risk....
