[ale] Mini-ITX mobo in standard case?

[Chris Woodfield]

I hate posting simple yes or no questions like this, but google is  
failing me...

Will a Mini-ITX motherboard (a Via EDEN in my case) mount properly  
into a standard ATX rackmount case? Those mobos make great firewall  
appliances, but I don't want to spend $200+ on a ITX 1U rackmount  
case when I just happen to have a spare ATX rack chassis available...
