Their ECC RAM recommendation also came with a qualification: basically, "If you can't afford it, and downtime to restore a backup is a minor inconvenience, don't worry about it." At this point time, if you're buying all new parts for a DIY storage project, 16Gb of decent non-ECC RAM is likely to be your smallest expense. But if you just want to get some light use out of a spare motherboard at home, less RAM is probably fine. Not necessarily a great idea, but not a bad one either. -- :: Brandon J.
