I named my old white bitfenix prodigy m “Baymax” because it was white and had rounded edges.

I did multi monitors for years and switched to a single 34" 3440*1440 ultrawide both at work and at home and I have never considered going back. I use a curved msi at home and a flat samsung at work. I would go larger size or higher resolution eventually but ultrawide is really nice for cad work so you still get a good work area without the sidebar eating into your view/modeling space. For normal use, I just do window snapping so I still get the function of two work areas.
