SQ difference - Raspberry Pi vs x86_64?

[hkphantomgtr]

I guess it'll have to wait until one of us tries it.

Also, not encouraged by what I have read about issues using a NVME for the OS.

What have you read? I'm seriously considering it as a next stage for my server.

It's a great deal easier than messing with the clocks 

Right, yet in my experience, the only significant improvement is replacing the crystal with ocxo clock. 

Battery power supply, adding power filter hat, vibration isolation, lan cable galvanic isolation, all help.  But none can compare the power of changing the crystal clock.  And 1 +1 is bigger than 2.
