I just wanted to join the thread and say thanks for posting this - I just successfully built my first FreeNAS build using the mobo discussed in this thread (ASRock E3C226D2I) and the same Intel i3-4130.
I'm using 16 GB (2x8GB) of
Crucial DDR3-1333 mhz ECC RAM, which, despite not being on the motherboard compatibility list, seems to work fine.
I went with a
550W Silverstone ST55F-G power supply and the associated
short cable set. It's probably overkill (the_tox's 360W PS is probably plenty), but it was the least expensive, short PS with fully modular cables that I could find at the time.
For my case, I went with a
BitFenix Phenom - I actually wanted the Node 304, but it was more expensive at the time. The BitFenix is larger than I actually wanted, but it does give me a lot of room to work with inside.
Finally, I just got 4x 3TB Toshiba drives that were on sale, configured in RAIDZ1 (I know it should ideally be 5 drives, but...).
So here's a question about this mobo - I flashed the BIOS to the latest (1.70) (via IPMI, which, not having had it on a computer before, is really nice!), and I can see that ECC is enabled, but how will I be notified if there are any errors? Will something show up in the FreeNAS log/console, do I need to check the BIOS, is it something that will be event log viewable from the IPMI interface (seems like it's only voltage/temp/fan sesors though)?
I have a Kill a Watt, so I'll grab some numbers this weekend and maybe grab some pics of my build.
