I need a mounting solution for some Raspberry Pi 4's. The object that I'm mounting them to us steel and being able to quickly move/remove the pi's would be useful. If I were to design and 3D print a case that uses magnets to mount the case, would the magnets (most likely round 15mmx5mm rare earth magnets, 4 per case) have a negative impact on the operation of the Raspberry Pi's?
Would magnets impact the operation of a Raspberry Pi 4?

Not at all. Static magnetic fields have no effect on the Pi. Some cases even use neodymium magnets for closures instead of screws or snaps.
And frankly, you'd have to be doing something pretty freaky with magnets that size to get any kind of adverse effect. Don't put your Pi on an induction cooktop.

No. It is not a remotely magnetic based storage medium, it is flash storage.
Unless you have rapidly alternating magnetic fields of the sort found in MIR machines and similar, there is no problem to worry about. A weak static magnetic field will not impact micro SD in any way.
It would be extremely difficult and rather expensive to set something up where a big magnet posed any risk to any component in a typical Pi use case.
However, a moving magnetic field will definitely, erm, help you find any floating GPIO pins you had made assumptions about.
I can see the clickbait YouTube video title now:
L00K!2! EZ SMD soldering using induction cooktop! (Also, wireless charge your iPhone with your induction cooktop and you'll never need to charge it ever again!)
What's the Ars equivalent of "hold my beer?" I mean we've had the feds called in before over forum experiments (including the Nuclear Regulatory Commission), but that seems like a poor and inconsistent way to judge the science challenges we occasionally ponder and/or attempt.
Just about the only thing that could cause problems is if you put a neodymium magnet straight on top of an inductor (e.g. in a power conversion circuit), saturating the inductor's core and massively decreasing its inductance.
That wouldn't occur unless the magnet is really close to the inductor, though, as in, basically stuck to the inductor.
