A colleague got hold of 2x 4U servers with 56 cores and stacked them with
disk and memory then found a wheeled 9U soundproofed case - quiet enough to
sit in a library and not wind up the librarians except on initial boot up.

Also small enough to fit under a standard desk if your standard desk is

I was involved in building a 64 node RAspberry Pi cluster for fun but it
was for fun only and not hugely capable. Raspberry Pi 4s might make it 
more worthwhile but still not convinced.

4 x Limulus machines and the support of this group - priceless :)

I suspect other institutional clusters have similar "the 800 pound (363 kg) gorilla has requested" scenarios.
