There are 8 individual devices inside the case that require power. The 6 major ones all feed into a power strip at the rear of the case, assembled with electrical outlet hardware (remaining 2 get power internally). The industrial looking plugs were bought new and shiny at Home Depot, then aged using hydrogen peroxide (an aluminum oxidant), sanding, and smudged paint.
The power cords themselves are all wrapped in a vintage styled cloth braid. Purchased from a bulk seller on eBay, the cord is made to look old but uses new safety precautions such as thick insulation and the addition of the 3 wire for proper grounding.
