I've built a few computers before, but mostly for Windows. I don't really count the raspberry pi as a build. I'm planning on setting up FreeNAS with 3 6 TB drives, 1 as redundancy if I understand correctly. Mainly setting up as a Plex Server and file storage. I may have some questions...
"Do IntelĀ® Coreā¢ i5 Desktop Processors support Error Correction Code (ECC) memory? The IntelĀ® Coreā¢ i5 Desktop Processors and IntelĀ® Desktop Boards typically do not support ECC memory. ECC memory is usually for servers and workstations rather than on desktop platforms, mainly due to the price premium of ECC memory and chipset support. Check with your desktop board manufacturer to see if ECC memory is enabled on your board."
I don't really know much about this type of thing. I just thought I remembered wendell of quain or someone saying that i3 supports ecc while i5 doesn't. Hopefully someone more knowledgeable can chime in.
Some Pentiums and I3's do support ECC, while i5's and i7's don't. If you want a processor with ECC support equivalent to an i7/i5, you'd need to go with Xeon E3.
Intel's consumer grade chipsets also do not support ecc (Z97, H97, H87, etc) so if you got a xeon e3 and ECC ram, the ECC feature will just be disabled. You'd need to get a Xeon, i3 (most), or Pentium (some), and a supported chipset to be able to use ECC.
As others have pointed out, i5 CPUs do not support ECC but a lot of i3 CPUs do. Alternatively, you can get an AMD FX processor (all of which support ECC) and a cheap Asus motherboard (Ā£45.56) that does as well.
Does anyone know of an cheap (<Ā£75) board that supports ECC and an i3? I would have loved to make such a build for the power saving benefits, but unfortunately I could never find one.
This might be relevant to the discussion of parts you're having here: This can currently be had for $300 (TD). Case, and all those parts mentioned included -- seems like a great deal for a starter server! (but it needs more SATA ports!). It seems like a lot of gear for a low price when you subtract he cost of the CPU on its own.
Lenovo ThinkServer TS440 Tower Server (I edited the list a little)
Intel Xeon E3-1225V3 3.2GHz 4GB DDR3 (ECC) 4x Hot-Swap 3.5" bays (another 4 also included but you need to buy a cage). DVD-Writer (2 optical drive bays which could be converted to 3x HDD bays). HD Graphics P4600 80 PLUS Gold PSU (server type, with a spot for a redundant PSU).
