I don't understand why they didn't use a Xeon e3-1545m, which is a 35-45 TDP part and has adequate graphics for the intended market. If it doesn't support ECC, there's no benefit vs the Intel Skull Canyon. I am in the market for a new dev machine, and I want Xeon and ECC. Just not enough good options currently (unless you build from scratch).

I'm putting money on something to do with ZFS. Turns out bit flips are significantly more common than had been thought in the past, which makes a error-correcting file system somewhat risky to use with normal non-ecc ram.
But if you use ZFS, chances are you will want to have lots of disk space and lots of disks, too. If so, why buy a small box?

On my current desktop machine (32GB ECC DRAM) I see a single bit error (corrected) probably every 18 to 20 days. There isn't an easy way to tell where that error hit in memory (you could presumably walk it back from the physical chip to the physical address space to the current page table and then back into virtual space and a process but that is waaaaaaaay too much work :-) Without ECC those errors would happen and…
How are you able to "see" the single bit errors? I had an ECC machine but I couldn't find any indication that ECC was working or that any bit errors happened. Reading this I thought the best I could do is to believe that workstation with ECC modules and Xeon will have functioning ECC: "Unfortunately, we have found that there is no consistent, conclusive way to determine if ECC RAM is working properly. ...We've actual…
I'm surprised the board/bios manufacturer couldn't answer the question, it's a pretty straight forward system.
[1] They show up as 'SBE' events (single bit error). An 'MBE' event (detectable but not correctable) would presumably result in an unhandled machine check and cause the kernel to reboot.

As someone who has purchased ECC SO-DIMM form factor RAM in the past, it is very much not cheap. (it was basically 4x the cost of ECC DIMM sticks)
That being said, they are more common with DDR4 now. Trivia: I think the pinout for DDR3 ECC SO-DIMMs are incompatible with the non-ECC ones!

They're not incompatible.

First footnote in the linked press release, justifying them calling it "the world’s first mini workstation[1]" [1] Based on publicly available information of workstation competitors as of October 3, 2016 with volume of at least 1 million units annually as of October 3, 2016 having ECC memory .
So they implicitly rather than explicitly say they support ECC memory. That's a first.
Personally, I'd wait for the tech specs page to go live before getting too upset about them not posting detailed tech specs.
Funny how while the PR spiel talks about CAD, the press image is of a stock trader desk.
They probably just wanted to show off the 6-display config for that photo. Stock traders are much more likely to use that particular display arrangement than engineers.

I assume that's just their way of pinning you to a load balancer.
Me too, but then try the same URI at www, www2, www3... it's a 404
But yeah, not much duplicated content unless you consider translations 'duplicates' (which it is, at layer8)

I have the Skullcanyon NUC, and this is not comparable. I've been waiting for someone to offer me ECC in a small form factor. This is the first time I've ever seen it.
I also have the Skullcanyon, as a laptop replacement machine. None of my previous personal computers have had ECC RAM, but none have had more than 16GB either. What is your use case that benefits from error-correction, if you please?
