SM Xeon-D is always a choice, $500 for the 4 core ones is not that bad... Also can have 10g onboard
X11SSV-Q looks nice but with a cpu no cheaper than the D1518/20/21
C2xxx have 6 sata but only 2 are 6G
J1900/N3700 boards either have 3rd party or slow sata, but probably the lowest power with no IPMI.
Would love to have a Xeon-D under 20 watts with SSD's only, don't think it can be done ?
Waiting for
@Patrick to give us the power info on the wave 2 SM boards (I am pretty confident the SM boards will be lower power than the other vendors as its more of a focus for them it seems)
