Personally, I would just use 16 power outlets and 16 PSUs.
Yes, it is elegant to cut the number of PSUs.
In a real production cluster though, think of the redundancy. Connecting
two motherboards to one PSU would have two nodes down for one PSU
failure.

Then again, we here in Europe had 240V mains power, so less risk of
setting your bedroom on fire, as we have lower currents.

An elegant solution would be to run the 12V inverter type PSUs, which
are intended to power in-car PCs

This one is only 120Watts, maybe not enough for your motherboards??
