that sounds like a potentially big issue. you mentioned that the board had damaged USB ports. which ports are damaged? are pins touching?
The ports in question have been removed from the MB. If I could identify the 5 volt traces I would cut them.
I have a Nephew I may hire to try some "surgery".
Mean while, its running without computation errors on V1.

How removed? USB 2.0 headers desoldered from the board? USB 3.0 header desoldered from the board?
+1. we need some specifics. "removed" is a little vague. could be desoldered, could be just yanked off the board with pliers, could be totally removed, could be partially removed, etc.

I am not sure how the USB headers were taken off the MB. I am not certain it was "unsoldered". It is clear the area has been "scraped" and lost some of the surface of the MB. My Nephew/Brother have agreed to take a look at it. I will (eventually) post a picture of that damaged area.
If I can get the boot messages to stop complaining about USB port overvoltage I would be a lot less hesitant to make it the GPU cruncher. Especially since the b450-F setup is throwing V1.0 errors again. And the Godlike wasn't.

My Nephew says it was not unsoldered. I will see about getting a picture tomorrow after the plumber visits one of my constipated toilets.

In honor of it being Friday the 13th. And having bought my 2nd PowerBall ticket in a couple of months I thought I would start off a conversation on a "Fantasy" level CPU crunching system. I expect to have one or two Rtx 3080 ti's on the system too.
My interest would be in a Dual CPU, Epyc motherboard-based 3rd? GEN system. I think. However, in the Interest of examining "all" possibilities, you are welcome to offer a shopping list of Intel and/or ARM systems too. Prices would make it feel more real.
So what would be the "best" EPYC motherboard for a civilian, non-data center environment? (eg. Not too noisy).

I don't see how this question is meaningfully different than the last X number of times you've asked it.
Okay.
Here is an example of an MB (review) that combines some of those ideas. It also, alas, has the cooling issue you pointed to. But it IS an E-ATX form factor.

you need to refine and declare your exact goals and constraints. "best dual EPYC" board is incredibly vague and there are a lot of factors to consider. dual 8-core EPYCs will not be as demanding as dual 64-core EPYCs so things like needed cooling and noise will vary greatly. then you have to decide if you want EPYC Milan (7003) support or not. most of the board models are segmented to 7001/7002 support or 7002/7003 support, but not all three.
Supermicro: H11xxx = 7001/7002
AsrockRack: EPYCxx = 7001/7002
Supermicro: H12xxx = 7002/7003
AsrockRack: ROMExx = 7002/7003
there are NO dual-EPYC boards that are standard ATX size. they are ALL either EATX, SSI-EEB, or some proprietary form factor for a specific server chassis. andthey will all be expensive. you don't have many choices for dual EPYC boards even in the larger EATX/SSIEEB form factors.
I feel like you're looking for a $300, std ATX, dual-EPYC boad. it simply doesn't exist.

"Scraped" sound like you
)
"Scraped" sounds like you removed some of the SMT devices near the USB headers. Probably the PPTC zener or bypass capacitor.
This pdf shows some common design layouts for overvoltage protection and current detection on USB ports.
USB circuit protections
If the scraping bridged the +5V to the Data +/- lines you killed the PHY port on the USB controller.
If the +5V shorted to ground then you should have blown the port fuse or if a PTC device it should reset itself if the short is removed.
A picture would really help.
