Building an Amiga PSU around an RPT-75B power supply

A lot of people use Meanwell power supplies as the replacements for the poor quality ones that came with the Amiga. Typically, the 50W variants such as the RPT-60B are used because it fits nicely inside an original Amiga power supply. LinuxJedi wanted to see if one could use a 75W PSU for heavily upgraded Amigas.

The RPT-75B is a medical grade open-frame power supply rated at 72W. It provides 6A on the 5V rail, which should be plenty for PiStorm32-Lite with a Raspberry Pi 4 and other upgrades.

The hope was that this power supply would fit in a regular Amiga power supply case, unfortunately it is ever so slightly too long. So, LinuxJedi decided to design a new one.
