Rodrigovr is actually right, to a point. You do want to hide everything that you can. I have been racking eq and doing wiring work for 20+ years... Use cable ties, not velcro, or wraps or anything like that, just plain old cable ties. I know, if you have to replace something or move something you have to cut all those ties... YEP thats right. Big deal. Just tie it all up again and do a better job each time you have to do it. You want to keep power separate from everything else.
And thats a great idea to be able to turn off stuff you don't use all the time with diff power strips, I do that myself.
You may want to use a mounting head cable tie and screw stuff you your actual desk. This is the kind of tie

BUT if you don't want harm your desk at all. Just leave it hang and lay on the floor and make it look at nice as you can. Don't use tape, or sticky strips, or sticky cable mounts, because NONE OF THEM WORK. About two days after you anchor something it will come off, trust me... Basic rule of thumb for cable work, if it seems like its going to be way too much work and a big pain in the ass, then your doing it right and it will look great in the end. And just remember I have done this with 20+ devices in a 72u rack (over 6 feet of eq...) and you could NOT see any power cable when I was done and all the network, KVM etc... were ladder wrapped and the rest of the ties were about 1ft apart... Took 2 days to do one rack, but it looked great when it was finished.
