I've got one, plan to make it my home NAS. Not yet built, but plan is: Solaris 11 Express with napp-it. 5 x 2TB Hitachi 5k3000 in RAID-Z1 (5th drive in IcyBox insert for ODD slot) 8GB ECC unbuffered RAM USB stick for OS 2 port internal SATA card (currently looking for one based on JMicron JMB362/363/366), or worst case will go Silicon Image Sil3132. I don't plan to do the hacked BIOS flash. I'll need to find a half-height bracket for this card. I will monitor ZFS memory usage. If it gets out of hand I'll consider adding a SSD as L2ARC, but likely that won't be required.
