Guess there is no reason GROMACS wouldn't run on a Raspberry Pi 4.

GROMACS can be compiled for many operating systems and architectures. These include any distribution of Linux, Mac OS X or Windows, and architectures including x86, AMD64/x86-64, several PowerPC including POWER8, ARM v7, ARM v8, and SPARC VIII.

Still, you would have to find a lab willing to make projects for something that might have a small number of donors.

Small ARM based computers just don't enough total oomph to run Fah projects. Even with recompiled Gromacs, the other dependencies just aren't there.
Small board computers are great for many tasks, but by nature are limited in total power compared to PC and Mac.
Boinc is a great alternative and even on fast phones/tablets with better oomph, the processing at kg es much longer than on PC.
