Here's mine. There are 6 power bricks at the bottom of this rack, and a 13 port powered USB hub. I have a snake that takes the HDMI, 5 USB ports, 12V, and backup audio for the piano. The back of the rack needs a bit of a tidy up, and I need to extend the ADAT outputs to the back panel.
Powered speakers plug in to the back for both power and audio, so I just need a single power socket.
I had the little digital amp anyway and it fitted in nicely. I can use that to run some JBL control 1s I already have, for a monitor for example.
When with the band, I plug Inputs in the front of the rack, and outputs at the back.
When at home, I plug everything into the back, so the front is tidy.
There's also a network switch/WiFi access point in the rack.
