This is why I ultimately ended up buying an HP ML10 for my FreeNAS box, $300 for a Xeon E3-1220, board and iLO ended up being cheaper than buying a barebones + the CPU (which is just shy of $200 retail). I would like to have something that supports more memory, but to get anything with more sockets or support for larger DIMM's you start looking at the Broadwell-E or Xeon-E5 chips and those are considerably more expensive (my ThinkServer TD340 cost me $700 as an open box with a E5-2403v2 and 8GB of RAM installed).
If Zen client chips have full ECC support and can handle 64GB of memory I'll be sold easily on an upgrade for my TrueNAS box, then I'll anxiously await some lower-cost (4/8c) dual-socket server CPU's and swap out my TD340 with some supermicro barebones build.
Do you know how much power does it use?
If so, could you add some details (number of HDDs, typical load - light, medium, heavy)?
I'm looking into building a home server and would like something decently beefy, not too power hungry and possibly with ECC.
I know the ML10 only has a 300W PSU, but I haven't bothered to take a kill-a-watt as the ML10 itself would be outshined by the rest of my lab gear.
The E3-1220 is usually idle and frequency scaled back unless something like a ZFS scrub is running, I've got ~45W of PCIe cards (SAS HBA, 10GBe NIC and 4x1GBe NIC), 4x8GB sticks of DDR3 UDIMM's probably uses 12W.
I'd say without drives it probably draws no more than 150W on average, unless I'm doing something CPU intensive. My drives all sit in an external SAS enclosure, since I wanted more than 4 drive bays that the LFF expansion bracket provided.
Anyway, the ML10 is pretty decent for light-medium work. It's got 4 really fast cores and 32GB of RAM is adequate for most home server use (this was why I got the TD340 though, I've got 72GB in it) - just beware that the Gen1 units don't include the drive bracket so if you want more than a single HDD you have to purchase one or get an external SAS enclosure.
EDIT: the ML10 is basically silent too, even under load - I can't hear the fans unless I try (though my SAS enclosure makes up for this by being the loudest bit of kit in my lab).
If Zen client chips have full ECC support and can handle 64GB of memory I'll be sold easily on an upgrade for my TrueNAS box, then I'll anxiously await some lower-cost (4/8c) dual-socket server CPU's and swap out my TD340 with some supermicro barebones build.
