Just wanted to share. Setting up a linux workstation based off the XPS 7590. I have completed the cable management and system upgrade itself. Just working on the networking portion of the build now. Stay tuned.
Also, laptops can go on arms too - real space saver. Amazon arms are rebranded ergotrons, and pretty good for the price. Just check the manuals before you buy because the mounting mechanism might not be able to attach to your desk (if you have a desk stretcher board close to the edge or a metal stabilizer or some such thing)
Edit, yeah looking at your desk it might be tricky, metal frame looks really narrow
