ECC worth it for a file server?

[somename]

I'm thinking about updating my home file/backup server, and I'm thinking about going low power route. It looks like I can save about 50-70W if I use 740g or g31 based boards over typical server boards.

Only thing holding me back from switching is those type of boards don't support ECC. Power saving I would get from switching would be non-trivial, so I'm leaning toward swtiching. I like to hear some argument for keeping ECC for my server though if any.

If this was for a business, I'd say, stick with real hardware. But since it's for home, ditch the ECC.
