We invested in the Vitsoe shelf system in our study/work room after we finally managed to buy our home. I highly recommend it. You can do all kinds of clever stuff with it - I have a desk but for a while I was considering a desk-less setup with the various tilted shelves for gear, and then freestanding monitor stands. I think it would work really well.
It’s also extremely well made, looks great, easy to reconfigure, etc. After years of moving Ikea shelves from apartment to apartment these are a dream. I am a fan of Ikea stuff (most of our furniture, cabinets etc are Ikea) but these are worth the money, for a room that we use so much.
