Nexenta home server
Just thought i would post my setup, running nexenta as a home NAS. I am running nexentastor 3.1.2 on a supermicro X8SI6-F with a Xeon X3440, 16GB ECC kingston memory, 2 ocz vertex 32GB SSD's for OS and 6 2TB seagate barracuda hd's in 2 raidz1 vdev's.
It took me quite a bit of tinkering but i finally got SABnzbd, Sickbeard, Couchpotato and mysql (for XBMC) working. Also using it to present a iscsi device to my main pc and redirect my desktop, documents etc folders to a zfs share so i can make full use of zfs snapshots/previous versions.
The motherboard is great since it has IPMI and a built in sas controller. The Xeon is a bit of overkill in this scenario since it never goes above 15% even when parring/rarring. A Xeon is probably best used when using the applicane in a ESX setting.

Just curious, why did you pick 2 x raidz1 vdevs? Do you need 8 TB of storage? You'll get the best performance with a single RAID 10 vdev but you'll only be able to use 6 TB of storage (still plenty of space though). When using slower SATA disks I naturally gravitate to RAID 10. Also, when supporting a VM farm, RAID 10 is the best option. At home you may not have a write intensive I/O workload, so raidz1 should be sufficient. Isn't ZFS great! It gives you so many options. You could even have gone for a single 6 disk RAIDz2 vdev - this might be the safest option for home use if you never plan to add more disks to the vdev.

Tought about it for ages. First i wanted to do raid10, but then i realized that with my workload speed is not a big issue (since i am not using VMware). Then i figured i would use raidz2 because of the double disk failure and it eliminates the need for a hot spare in my setup. The problem with this is the expandability. I will probably want to expand my zpool after a year or so (or sooner), but do not want to have to buy 6 disks at once. Also a single disk failure will just mean shutting my system down, going to the computer store and buying a new HD. Not a big inconvenience compared to the chance it will happen. So in the end i choose for the solution that will give me the cheapest expansion path (adding 3 disks for 4TB), while also having some sort of middle ground performance wise (twice the write performance compared to 1 raidz2 vdev).
before you make a choice on your vdev setup, make sure you have your requirements and priorities clear! You might end up with a completely different setup than you imagined (like me) :)
