Searching for a new motherboard

You need to differentiate between registered and unbuffered memory.

The ECC memory that the AM4/AM5 boards discussed so far are taking is unbuffered. It does not come down from big servers, which use registered ECC. Unbuffered ECC is fairly expensive, registered ECC is cheaper used.

To complicate thing, there are Xeons for unbuffered memory and single-socket.

Yes, all factors to consider. A lot (perhaps the majority) of server grade ECC ram is registered. You need to check what the particular motherboard supports, it will be determined by the chipset they've used, and how they have implemented it on the board.
 
Myself, I do not care if old gear burns more power.

A cost analysis of power vs new equipment costs might show that a very long time is required for break even.

All of mine go auto off at bed time anyway.
 
I'm actually tempted to get one of those Jingsha boards and try building one. It's overkill for what I'm doing at home though, at least, at present. It's interesting to find out what is available nowadays, I haven't looked at the dual xeon thing for a few years.

In the UK, we are now paying just about the highest prices for electricity in the developed world, so maybe I'm a bit more cost conscious than I might be elsewhere. Our elec. prices are supposed to be about 4x what the US pays, I think I read recently, although I think that's for industrial elec.

Google says UK pays 26.11p/kWh. This is lower than *average* California price of 0.35$/kWh. In fact I was paying about 0.60$/kWh. I now have solar panels + battery (mostly due to PG&E being so flaky) and pump energy back into the grid but they don't pay anywhere near what I paid (plus they changed the rules to benefit them....).

If you burn 100W *more* that translates to about 876kWH/year or $219 (@ $0.25/kWH) more you pay.

13 / 14th isn't bleeding edge (You have Core Ultra 1 and 2 series) and no sane person would put a 150W+ TDP CPU in a NAS/Gateway (which is what's being referred to) for home usage. The T-series for example were never affected and much suitable in that regard.
..and I can hardware see how getting a "franken board" from Aliexpress with zero support and security updates would be a good idea even if its cheap not including power usage.
A 10 year old CPU with a 120W TDP is hardly a good deal, Passmark isn't the holy grail but it can give you an idea and two are pretty much on par with a single Ryzen 7600 which uses ~1/4 of power and isn't EoL

All AM5 (7000-series and 9000-series) support ECC official, on AM4 it's only the PRO models (officially).
On Intel you have Pentium/i3 (depends on model) and Xeon paired with workstation/server chipset (so no B/Q/H/Z-chipsets).

Sadly the H4-Plus is out of stuck which could've been a very good contender, neither do ECC but IBECC which is like psuedo-ECC.

Ha, egg on face, I should have read the OP's whole post. Yeah, scrub the dual xeon for your NAS/gateway, you can do that with an N100. 😂 That Odroid box would be ideal.

Wow, cali sounds expensive. I know that my own domestic elec. bills have more than doubled in the last 3 years. Everyone I know has been trying to save money by cutting down what they use. Prices here went through the roof once the ukraine war started. Gas and water, too.

The rate per kwh isn't the whole story either, they also sting us with a 'standing charge' which has also more than doubled. You have to pay that each week before you use a single kwh, just to stay connected.
 
Hi all, and thanks to all of you for your opinions. I have some stuff to research now and I really do appreciate the input. I should clarify the need here.

I had a failure on the current gateway which caused some downtime - luckily it was easy to solve after a good night's sleep. But it did raise the issue that the gateway is about ten years old. It would be good to have a backup ready to go should it fail again. An
even older system here hosts the ZFS raid2-z NAS system.

I may not need ECC on a new system after second thought. I do prefer Intel NICs, thanks for pointing that out. Some PCIe expansion slots will be helpful, especially if the motherboard has only one NIC. I may wind up with 3 NICs ( does anyone still do DMZs for security? ) And this system likely will receive another ZFS raid system. This will be my first FreeBSD system with ZFS for the root; looking forward to BE. I think integrated video/graphic is good for me as I don't want to waste a PCIe slot on that. This will be run as a headless system, and video is likely to be attached only for initial setup and later to debug problems ( like failing hardware ).

I will NOT be playing games so I don't need any fancy graphics, nor will I be running a graphics desktop. No LLM work on this machine, but perhaps a jail or two. I think I can run any VMs I need on a different host.

Since I need a reliable machine I will be buying new equipment. There really isn't any heavy computing going on here, so I do not need a tons of cores, and I think 32 GB of memory should do. It will be powered up 24/7 being a gateway, so that is a vote against the biggest and fastest CPUs. In the future I may deploy a web server, mail server and DNS, also I have a SDR (software defined radio) that I will make available. Still thinking about how to deploy these "services" for the outside. I was lucky enough to register some IPv4 addresses long ago, but I have a lot to think about before those become visible. Security is an "interesting" problem -- lots to learn there.

Again, thanks everyone for your suggestions. I really do appreciate it.
 
Hmm, I should have read your your original post more thoroughly, I completely missed the "gateway" part.
Two suggestions:
1) for a gateway only - buy a secondhand / reburbished / outlet small form factor desktop (like a HP ProDesk in size). Do your homework first - make sure the model you choose has two network interfaces and space for an extra PCIe card if you need three network interfaces

2) for a combined gateway / NAS - buy a small office desktop / minitower / full size tower, put in a cheap sata card if you need extra ports, and extra network cards if needed. As before do your homework - make sure that it has space for the drives you plan on, and that the power supply can handle the load.
(some known brands use non-standard psu's in their office line of desktops, making it hard to repair if the psu dies)

This (obviously) only makes sense if the availability and prices are ok in your local area.
 
I prefer my main system to be separate from a gateway (firewall) machine. The gateway machine should always be uptodate to deal with any security patches but that will often require reboots but other than that it should always be up if you have other machines in your home (likely, if you are streaming video/audio like most people + have phones/laptops/tablets + may be security cameras and what not). The fileserver should be as stable as possible and need not always have the latest updates. Your primary machine need to be only up when you are using it but you may put heavy loads on it. Combining the primary machine + NAS + gateway is asking for trouble as when that goes down, everything goes down (& you have to rely on the phone or tethering to access the internet).

A separate gateway machine need not be very powerful. Plus you can update them all independently.

In general I want my service machines to be install and forget for the most part. Given that suspend/restore on freebsd has never been totally stable, I leave them on all the time.

And it is not a given that a new system would be more reliable!
 
I see the requirement was backup gateway and possible NAS.
I agree so much with Above Post. KISS. Firewall is just a firewall. SSH here has to be fine tuned to allow inside traffic only.
No extraneous servers running. I don't even install a Munin collector because it installs python. I will not have that on a firewall.
Tripwire, dnsmasq and a few other ports... It is an appliance not a toy.

I have Two ISP's and one main firewall. X9SRL with 40G Chelsio.
One ISP connection is configured as DMZ for tarpit and the other is my daily driver. I swap them around.
My backup 'gateway' sits on a shelf incase main one dies.

I have big fileservers and I have little fileservers. Some I turn off when not needed and some run things like Munin and syslog-ng and are multifunctional.
