Well, now that the cooling part is done, we need to solve the power supply,
the FPS signaled by DAN unfortunately did not guarantee all the necessary energy,
after some research (thanks to various users of this forum)
i intercepted this fabulous
ENHANCE 600W
modified by the guys from GEEEK (ask CIRO, a great guy!)
Unfortunately, it is a little high once the power is attached,
so choice 1: cut the end of the power cord slightly,
or choice 2: open it and change the output,
the 2 was the most sensible solution for me,
also because it has me given the opportunity to change the interior fan
with a fabulous little gem NOCTUA NF A4x10
(...so i modded a modded psu)
To fix it, I simply screwed 3 small standoffs into its existing holes,
so I still have a minimum height needed for ventilation (the DAN A4 has very low feet)
and also allowed me to hook the side cover bulkhead of the case in his accommodation
... unfortunately I had to make 3 small holes at the base at the standoff,
necessary sacrifice, now it is impossible to move!
