Thank you plonk420 for bringing that photo to my screen.
It is a thing of beauty.
Very tidy indeed.
Taking a close look at that setup, I think you will find that it is in fact an LTSP cluster ... it all bootstraps and runs from 1 HDD
(I'd prefer 2 HDDs in a hot-swap RAID with a 3rd for regular physical swap-out)
That cuts a big chunk out of the cost.
They did a neat job with the reset buttons
(the fine green wires running to the press-switch arrays)
With that many PSUs, it is worth looking into implementing a DC power-rail (One big PSU with lots of power cables)
sigh ... yeah, if I had the dosh I crank up one of those PDQ.
