I move my stuff around too much to invest heavily in studio furniture. I ended up building almost all of mine using cabinet grade plywood and hairpin legs (just like the look of them and they are inexpensive).
Take two pieces of 3/4" birch plywood, glue them together face to face, attach legs, done. I have a large 60x30" desk with 28" legs and a smaller 20x48" sideboard table with 24" legs for my eurorack. My plan is to build a 24x60" sidetable with taller legs so I can nest the two sideboards together with one surface above and behind the other to help hide cables and give a nice surface for tactile stuff.
I built a 12u 19" rolling rack for my “studio” gear that matches the desks perfectly - it is still mostly empty but I keep a Furman PSU, Behringer ADA, and patchbay in there. It looks like this but completely DIY and around $50:
My only thoughts on the Argosy would be how would you work between the two rack units? What if you wanted to patch them together?
