SFF Build Ideas

[RedundantWren]

Greetings all,

I'm trying to put together a desktop ITX SSD array, but the parts are few and incompatibilities are many. Worst case, I will just continue my current system of "random pile of external drives I disperse throughout my living space", but I'd really like to move away from that. If anyone has any suggestions, they would be greatly appreciated.
Here is a rough outline of what I have decided so far:
8x SATA disks (Probably 870 Evos bought separately, unless something else speaks to me) in RaidZ2 or Z3 in a Silverstone CS280
Probably 32GB ECC in one stick (e.g. SuperMicro 32GB ECC DDR4 3200, whatever is compatible with the MB) and add more as needed
Corsair SF750 (I would get the 450 but it's not available anywhere that I've looked).

As for a MB/CPU, this is where my search has found significant difficulties. I just need the combination to have ECC support. IPMI is a nice to have, but if not, I'd like graphics so I don't need to shuffle drives around. So far, here are some I've found:
AsRock Rack E3C256D2I (LGA 1200) + A used Xeon E2314 on ebay
Supermicro MBD-X11SCL-IF-O (LGA 1151 300) + LSI HBA + Some i3 or other used xeon

Is there anywhere I can get a comprehensive list of intel cpus with ECC support (ideally also sorted by socket)? The intel website is busted and won't let me search their products. AMD is another option, but I cannot figure out their maze of "ECC-maybe" mb/cpus and broken vendor search functions.

So far I think this one is the winner out of all of my ideas:

Motherboard	ASRock C246 WSI ITX
CPU	i3-8100T
Memory	1x 32GB DDR4 2666 ECC Reg
Disks	8x 1TB Samsung 870 Evo (z2 or z3)
Boot Drive	A tiny m.2 drive (with the config mirrored on a usb drive?)
PSU	EVGA Supernova 450 GM
Case	Silverstone CS280

Currently, I'm torn on the cpu choice, namely 8100 or 8100T or if I should pick a xeon (e.g. E-2104G). Any suggestions (on any aspect)?

Also, I forgot to point out: is 450W sufficient? It seems so to me, but I'm not exactly an expert on this topic.

I can only say that I use Xeon when I can (pretty much all models support ECC when the board supports it).

The models ending with G (like the one you mentioned) have onboard graphics.

I don't know enough about the i3s to tell you which is better or if it's best to avoid. I understand they do have ECC support at least in some cases.

You will want to be careful to select an M.2 that is both the right size and also a true NVME (not SATA) interface, otherwise you lose one of your onboard SATA ports to it.

I don't think you really need to consider a USB backup of config, but saving a config backup regularly off-box is a good idea and can be done by using @joeschmuck 's script (https://www.truenas.com/community/resources/multi_report-sh-version-for-core-and-scale.179/)

450W may be pushing it, but with no spin-up, you may get away with that. 750 will be good and will potentially be more efficient running at lower % of capacity.

Proper Power Supply Sizing Guidance

I've seen about 1,000 threads like this one where people decide that they can power a dozen hard drives off a 360 watt supply. DO NOT DO THIS. I've seen another 1,000 threads where people decide to buy the cheapest power supply that they can...

Just a short side-note: if I remember correctly, C246 does NOT work with RDIMMs. You may need UDIMMs with ECC for that MoBo/CPU combo.

 

[Etorix]

Correct: Xeon E3/-E-2000 are Core CPUs with ECC and only support UDIMM. i3-8100 does support ECC, but you may drop the 'T', which brings no useful feature.
For RDIMM support in mini-ITX size, and with at least 8 SATA ports, look also at Atom C3000 boards (Supermicro A2SDi).

With SSDs only, 450W should be overshoot already.
