in a chassis with jet engine FANs + Air shroud you should be fine with the VRMs.
As I said the plan fell apart because by the Time I got the Month's Salary the Chassis went out of Stock ...

And I was NOT planning on leaving the Backup Server ON 24/7 let alone with an EPYC Motherboard ;)

Probably don't understand enough. Why would you consider Epyc board for backup server at all? The electricity cost would not worth it I believe.

No, it's not worth it. EPYC is actually more efficient than those Xeon E5 v3/v4 I was eyeing for the Backup Server or my Desktop. The EPYC I think can Idle as low as 60W ...

That would be CPU alone, no? What I read so far, whole system with Epyc would be ~150W. My work machine idles at ~60W which is a lot for bakup server for me.

Try with 36 HDDs then let's talk about those "big" 60W ... With a Figure of 10W/HDD at a minimum it would be 400W with 36 HDDs. Plus PSU efficiency on top of that, so maybe 450W or so.

Those 6TB SAS HDDs at 30 EUR/piece were too good to pass on. But now it seems that I need to spend a whole lot more in term of Chassis & whatnot. Sigh.
Yes, really nice price. I currently have 6x 18TB in RAIDZ2, which is enough for my needs. Maybe I will upgrade to 8x 18TB now when zpool resize is an option with ZFS 2.3. Have them all inside my working PC which I hardly power off anyway.

I was contacted about that new MB and looks good.

South H12D-8D SP3 motherboard performance=Supermicro h12ssl-i support 7002-7003

SThe 12D-8D motherboard adopts ATX board type, 14 layer PCB design, equipped with 9+5-phase 60A DrMOS power supply, and has 2 sets of EPS 8Pin CPU power supply interfaces.

The specific expandability of this motherboard is as follows:

Memory:
8 x DDR4 (1DPC), up to 3200MT/s;

PCIe slot:
4 x PCIe 4.0 x 16.

Storage:
3× M.2 2280,PCIe 4.0×4;
3 x SFF-8643 4i, PCIe 4.0 x 4, both support 1/4 SATA III 6Gbps;
4× SATA III 6Gbps

Network:
2 x Intel I226-V, supporting 2.5GbE;
1 x Realtek RTL8201F, supports 100MbE, IPMI management network port, requires BMC module.

Audio:
Guanghua Chip (Shuhua) CJC6811A USB Digital Audio SoC

External I/O:
In board connectors: 1 set of USB-A 5Gbps, 1 set of USB-A 480Mbps;

Rear interface: 1 x VGA (BMC module required), 2 x USB-A 480Mbps, 4 x USB-A 5Gbps, 2 x 2.5GbE RJ45, 1 x 100MbE RJ45 IPMI network port (BMC module required), 2 x audio jacks.
I don't like the connectivity choices they've made here. I'd much rather have all the PCIe slots available to use versus the one additional M.2 slot over the Supermicro boards. It's a terrible tradeoff—and they're not even 22110, so say goodbye to support for most SSD options that provide PLP... Oh, and there definitely should, at least, be another variant available that offers 10GbE instead of 2.5GbE—especially with PCIe slots already being limited.

It also requires an additional BMC module to fully support IPMI. Where is this available from, how much does it cost, and what connectivity does it have (PMBus, I hope)?

IMO, @Tugm4470 is asking far too much for this Huananzhi board as its feature set isn't comparable to other options that are similarly priced and its longevity is in question due to it not being from an established brand with a proven track record of providing good support for their products.

Edit:
To those brave enough to purchase one, please be sure to share your experiences with us. I'm particularly curious about the BIOS functionality it offers.

So the H11SSL-i Rev. 2.0 would be a better Deal, even if it doesn't support PCIe 4.0 ? Does it Support AMD EPYC Milan though ?

I upgraded my fileserver in 2022 from a xeon e5 v4 4core cpu + supermicro x10srl + 1x 32GByte RDIMM to an epyc 7443p 24 core cpu + h12ssl-i + 8x 16GByte rdimms. Chassis (846 with sas 3 expander backplane), 22x 16TByte hdds, raid controller and psu stayed the same.
Difference at the wall were 25-30 Watt more under it's normal load. That's 20more cores, 6 more rdimms (higher clock, but lower capacity), pcie 4.0, 88more pci lanes
