After too many years of frustrated limited access/ventilation:
I cut huge access holes in the back of my cabinet, for hands, arms, head if needed, access, lots of ventilation. The problem is seeing the wires against the white wall behind.
I made a floating back panel of matching color.
I hung it loosely 1-1/2" behind the back of my cabinet, it slides/lifts off, have at everything, then hang the panel behind the wires, push/roll the cabinet back in place.
Black might work, I had a matching wood panel from the back of the old upper cabinet I removed.
The cabinet floats 1/4" above the floor on concealed wheels, 4 of these
