The 3 expansions slots on the S3 is more for triple-slot GPUs or even a switch for lighting/etc,

edit: it should be noted that while the board may "fit", the motherboard tray won't fully support it as there's no standoffs for the lower parts of that board, leaving that portion of the board without support.

I'm pretty sure you've never heard of it because thats probably not the proper name. I believe this would more correctly be called a mini-DTX motherboard, basically mini ITX extended for 2x PCI-e slots... though this actually looks like it might be even a tad longer than mini DTX. They're not a very common form factor in the consumer market, which is a shame because its really nice for NAS or HTPC boards where you want something more compact than mATX (especially in depth), but need more than just 1 slot (i.e. for 2 SAS cards, SAS + NIC etc)

I went with the LSI 9211-8i since that was the go to HBA card according to people in the FreeNAS community. They get so particular bout hardware and even the firmware the card is flashed to it's insane. Like, if you're on a newer firmware than the version Freenas wants, the UI will blink an amber light at you and most people will actually recommend using the older version rather than the newer one.
It's been a while since I check but the 9207 or 9300 may also be good cards.

I've been thinking about pulling the 9211-8i HBA and using the motherboard SAS headers to run the hard drives and then maybe installing a 10Gig-e network card. Actually, I'm certain that's what I'm going to do as soon as a 10gig-e switch comes down in price. I'm always constantly hitting the 1000 mbit connection limit.

I've had this setup for almost 9 months now and in retrospect, if you're planning on building a large multi drive NAS, go with an actual ATX or EATX server motherboard. I've got 6x 4TB drives in there and 32GB of ECC ram. The E3 v3 Xeon is limited to 32GB of ram which caps my future expansion possibilities. 6TB and 8TB drives are out now and without a doubt 10TB drives are on the horizon. for a 6x 8TB or 6x 10TB setup, you should have 64GB of ram minimum and the E3 or the mini ITX motherboard wont be able to take all of that ram. Micro ATX motherboard can't either. There's a couple matx motherboards with 4 slots but they're not equipped for E5 xeons so again 32GB cap.

You would really need a server motherboard that supports the 8 dimms or 16GB sticks or both to go with any capacities larger than 32TB of storage space. That said, if you dont plan on upgrading the capacity, a little box like this is amazing smile.gif

I'm building this MONSTER. The Super Micro board I've chosen can support 64GB RAM, if it ever comes down in price (16GB ECC SO-DIMMs are still almost $400 each). I was really close to ordering that same S3 case (I have an STH10 already, and Case Labs are right in my backyard here in Los Angeles), but then I went all mental with this idea of my own network rack.

The bottle-neck for my build will be the PCIe lanes. With 16 SATA drives, it works out to about 150-175MB/s per port, but then again 5,400 RPM WD 6TB drives kind of max out around that same rate. I'm planning to post some performance numbers once I finish the build. Hopefully, I haven't unnecessarily left a lot of performance on the floor. I don't actually require incredible performance here, the goal is just a feature rich NAS with a massive storage array leveraging the ZFS file system for long term data integrity. Down the road, if the performance isn't good enough, I can always build a new server.

I'll be a little jealous, 10GbE is awesome. I'm planning to use link aggregation, that Super Micro board has 4 on-board Intel NICs.
