Atom boards with more than 2 Sata ports
I'm planning to build a DIY NAS. The reason I want to do DIY is because I have everything I need but a motherboard. I am only going to use 2 3tb drives to start with but want some expansion capability. Are there any atom boards with more than 2 Sata ports under $100? I've seen the supermicro ones with 6x but they are a bit more than I'd like to spend.
