The overall component layout appears to be very good. Not having a modular cable receptacle board at the front of the power supply allows the

As we mentioned earlier, the small switch on the right side of the vertical PCB, appears to be the switch referred to in the manual for turning on or off the independent +12V current limiter circuits, resulting in a single, high-capacity +12V rail. There are two small holes in the side of the enclosure, which are covered by little, round “void your warranty” stickers. These provide access to the switch and a small pot on the left side of the board that is most likely used for final voltage adjustment.
And as you can see in this photo, the main PCB is clearly labeled for +12V4, +12V3, +12V2, and +12V1 outputs.
