I have that motherboard and very happy with it

I did that leap a couple moons ago and it’s all fine with AMD.
However Asus (I have the same mainboard sans the wifi) will install a ton of crappy Asus software by default. It can be switched off in the UEFI, which I recommend to do before installing Windows. Then use an alternative software or hardware for fan speed control.

True! I noticed that with my previous boards. The hardware is top notch, but a lot of bloatware… Even the RGB LED Aura Sync caused issues in games.

Never occurred to me that the mobo would add junk-ware. Is this mostly a RGB lighting or fan power thing? Guess I’d always assumed it was low-level software only used in the BIOS UI.
I have just set the fans in the BIOS and de-installed the software…

The UEFI kind of injects it into the OS. A bit backwards and I don’t like it. Of course it is on by default

There’s actually a few things AMD does better. After years of Nvidia I bought a 6800xt in February and it’s actually quite nice and more convenient to use. Makes you realize what an ugly mess Nvidias Software is.
I had one game (Sniper Elite 4) crash on me unless started in Windowed mode. That was reproducible and weird. Other than that no issues, and butter smooth when paired with a freesync 144 hz monitor.

The resizable bar feature is also there for nvidia in the mean time.
Yes, nvidia drivers are good and stable.
But the UI and settings dialogs, the screen recording features and streaming stuff - meh. It feels like a blast from the past.
AMD does that better, but then again it’s only a nice-to-have. Driver stability is more important.
Can’t go wrong with either, I’d say. The market still prefers Nvidia.

As my PC is integrated in my SimBox, that now has bass shakers installed, I worry about vibrations…
I will rebuild the computer box as I install the new hardware and I will fix my old mistakes.
I will attach the bottom plate to the SimBox structure with rubber dampers, but I am also considering screwing the motherboard to the bottom plate using springs.
I have made a test stand-off using two blind nuts and a spring…

What is the spring constant of those springs? How many springs? And which parts will be resting on the springs?
Then we can calculate their natural frequency and if that matches what the bass shakers put out, it is a bad idea

Ehm…
Basically everything that’s on the mobo.
You make it sound as if I don’t have a clue…which is more or less very accurate. 
Would it be better to put rubber or silicon tubes under the mobo screws…? Using a piece of tubing, as a stand-off?

Not my intention, I was just trying to share my thought that a mass spring system with low damping has a resonance. And it seems that came across, despite my cryptic phrasing!
I like your strongly dampened setup ideas, and am not qualified at all to comment on which specific implementation is best.
The point is, you can use springs, as long as you make sure that the damping is at least as strong as the spring. There are simple ways to measure spring constant (kg/cm or equivalent) and some simple formulae you can use to compare the two, but you probably intuitively know what is properly dampened and what will keep oscillating

Truth be told, you need to solve the differential equation for the mass-spring-damper system to know what it will actually do. What Troll is trying to do here is very hard with what he has available, so I wouldn’t expect too much. I think the best you can hope for in these circumstances is to form a mechanical low pass that will take the edge off of impulse type excitation. Dampening low frequency periodic excitation is way beyond what can realistically be achieved here.

No, no, no! I was just kidding! But I really don’t know anything about this. I appreciate your input!
So, if you try to translate that into a suggestion…?
Imagine a metal plate, that is attached to the frame by rubber dampers.
I then attach the motherboard to said plate with the above mentioned silicon tube dampers…? Should kill some vibes, right? Any chance it would hurt?
Trial and error. You will have multiple resonance frequencies anyway depending on which degree of freedom is being excited. Plus you have uneven mass distribution over your mainboard.

@sobek is right.
I should have known better, had lots of trouble in the lab with a multi-million euro fridge where we tried to dampen vibrations of 3 - 70 Hz.

Not the answer I wanted, but probably the answer I should have expected
But compared to hard mounting the mobo to the frame, metal to metal… Using some rubber/silicon between the metal hardpoints should dampen out some frequencies, right? Could it accentuate any vibrations?
Yes, the high ones more so than the low ones.
Yes, depending on which part of the mobo we are talking about and which degree of freedom (up/down, sideways, rotational), there could be all kinds of different resonance frequencies, but as long as that doesn’t lead to any hard surfaces making contact (like the ruber getting squeezed so hard that the screws bang into each other) that shouldn’t be an issue either.
If i were you, i’d start by running a decent amount of broad spectrum white noise through your shakers (careful not to bust them though) and see how much of that vibration actually ends up on the motherboard to see if this is even worth it. Since we are talking low end of the audible spectrum here, you’ll be able to feel the board vibrating. If you can’t, then this is an academic exercise in futility.
