OK...so the issue is you have a lot of stuff....and no logical functionality of its use of space.
Maybe you need to look at the logic behind the setting of a drumkit....or a pilot's cockpit.
Chances are it's a lost cause because you have no apparent flexibility in regards to the options of problem resolution.
Issue...
You have a lot of stuff.
You do not have enough space for that stuff.
Solution....
Make more space.
I'll type it slowly just so you don't miss the point....get a bigger desk...if it's a single-person workstation you need to be able to see and do/access everything with a minimum of movement/relocation...so it's simple ergonomics.
Bolt yourself to a chair.
Anything outside of your reach is useless.
Move it so it is within reach.
If your arms are short you will need to arrange things in tiers [likewise think synthesizer keyboards - they are tiered].
Only other options are to grow more arms...or hire a lackey to reach the bits you can't...;)
