I solved this problem many, many years ago, when I designed and constructed a custom console that held all my power supplies, my TC Helicon Harmony-M vocal processor, played a soft strip light on the keyboard for nighttime use, had a lighted sign on the front, and my Acer Netbook PC was mounted on the top. It takes up no more space than a standard arranger keyboard stand, and there was less weight to carry, set up time was less than 7 minutes, and it all folded flat and fit in the back of my Dodge Grand Caravan with stow and go seats.

The mouse for the PC was placed on a relatively small, wooden platform, held in place on top of the keyboard stand's right arm by the weight of the keyboard. Not a lot of wires showing, just three, and this photo was taken in the marina where I kept my boat just prior to doing a nighttime party.
