Right, but that's a pretty lame clock.

Also the only one so far I've seen able to support multiple PCIe.  The 
Supermicro is mini-ITX.  But the AsRock has some weird power arrangement

Yes, but that's a big wattsy thing.  The X10SRW comes in some 1U variants
that can handle two PCIe so it'd be an interesting router platform that 
does not eat lots of space.

Always an issue.
