We bought this for our kids "gaming room" and have two televisions mounted above it with three different gaming systems attached. The back has numerous knock outs that allow wires to be fished around. Assembly was easy, maybe 20 mins. We drilled holes the drywall behind our TVs and behind this unit and took the wires through the wall for a totally wireless look. This forced us to take the unit on and off the wall a few times to measure holes and move wires. The installation system makes it super easy to do that. I couldn't find another product that had the same level of function as this, even at a higher price point. This is particle board, but is heavy and was well packed.
