uh im pretty sure i saw a 3prong plug in the back which means its grounding the case,this means internal psu
The pictures you saw were mockups, the ports in the back were blank and so they photoshopped all of the connectors.
ET: Is the power supply integral to the box? Or do you have a separate power supply in-line on the power cord?
TH: Some of the power delivery mechanism is internal to the box, but there is also an external power supply that delivers DC voltage to the box.

The external brick is nice because it will keep a good amount of heat outside the box.
