The dual core Atom is a serious chip, I don't have that same
impression of the VIA chip. Also, the Supermicro MB has an x8 and an
x4 PCI-E slot, really opening up RAID card options. Two Gigs of RAM
should suffice for single-role server application, no matter the OS.
The advantages outweigh the disadvantages, and the price difference
looks to be around $20-30, not too significant for one-off purchases.

I don't know what processing load ZFS puts on the system... I assume
an Atom dual core would suffice...

The benefits are the four HD bays and the price...

Go to eBay and google "SuperMicro atom" you'll see this board in a
shallow 1u rack chassis for around $300, but no hot-swap, just one
3.5" or dual 2.5" SATA drives...
