Pros: AMD Fusion supports 8 GB of RAM - All Intel Atom boards support only 4 GB of RAM, which made them useless to me. Runs cool, fits great in an Element Q case. Ran FreeNAS out of the box with no problems. Plenty fast for my needs.

Cons: On-board NIC (Realtek 8111F) is not well-supported in Linux or BSD. I'm not even sure if FreeBSD drivers exist for it. Using any Realtek NIC for a NAS is a bit crazy, however. I used the PCI-e slot to install a $20 Intel NIC, which has rock-solid BSD support with faster throughput and less CPU usage.

Overall Review: I wanted a mini-ITX board that supported 8 GB of RAM (for ZFS) and was passively cooled. This fit the bill perfectly, and is running great with FreeNAS 8.0.4.
