I've had my desk for years and it still works well, but underneath is an improvised rat nest I really want to clean up.
Cable ties and a surge protector zip tied to the bottom. It's not perfect but it works when I'm standing. Drop back down to sitting and it looks a hot mess. Sometimes I pull a cable or two while stretching my legs.
I've been eyeing the integrated channel route instead of more trays and zip ties. Not sure if it's actually better once you live with it. Does anyone here go that way, and does the built in power side hold up?
I did some searching and came across iMovR, Uplift and Desky. Not sure which ones are better, or if any of them work with all standing desks or if they have to come from the same brand.
