ctnewbie - I've seen some kitchen desks that have a hinged false back in the knee hole area that is 3-4" out from the wall...all the cords go down a grommet from the desktop to the space between where they're all plugged in....wish I had a picture, but I hope you can understand what I mean. bestyears - I love how you have all the chargers labeled! I'm always trying to figure out which charger goes to which phone or music player or game device. I even have a labeler...why didn't I think of that?

Lot of ideas here... https://www.houzz.com/photos/exposed-electrical-ceiling-wire-phbr0lbl-bl~l_41462 200 pages worth supposedly.

Invest in some of the Velcro straps or plastic ties to hold all your cords together to make one length of cords to hide rather than a lot of stray cords. Use a power strip available at most big box stores -- one with a half dozen outlets for plugging in multiple electrical cords so you only have the one electrical cord going to the electric outlet to hide. https://www.bhg.com/shop/ge-ge-power-strip-surge-protector-6-outlets-10ft-extra-long-power-cord-flat-plug-800-joules-safety-locks-multi-outlet-wall-mount-white-14092-pcfd338f8a0d939373d7901b4c5a9dd38.html For your entertainment -- I like the city skyline. http://industrystandarddesign.com/11-sneaky-tricks-to-hide-those-ugly-wires-at-home/

People frequently say they are working with Pros when they are DIYing and are not. Because of the deserved heat level associated with not hiring a pro when they needed to. An electrical engineer, or a roofer is not a structural construction specialist, despite engineers thinking they know enough to remuddle the world. And then, they go on to describe situations that no construction Pro would ever allow to happen. Which betrays their incompetency to do the job. Or the total incompetency of the supposed pro involved. An architect would have handled the aesthetic and structural questions raised by the thought of the project. Trusses are not stick framed rafters, and cannot be thought of as stick framing. It’s an engineered whole system that must be linked together to work together for proper support. Those “drywall supports” linking the bottom chords are structural in a truss system that is meant to be covered with drywall. They lend required lateral bracing to increase rigidity to the support system. Trusses meant to be exposed have to be originally designed to have the strength and rigidity to be an exposed structure. There is no such thing as “just” removing the drywall and braces and having that be a viable structure long term. And that is just one of the telltales that indicate no professional involvement. Or, incompetent professional involvement.
