Here's my modest custom-built rig. Sorry I only have my phone's shitty camera and the lighting in my room is total ass.
I plan on buying or building a new desk once I eventually move out. I really want a sleek desk that's really minimal and not bulky at all. I hate my current desk because it's old and rough as hell, plus it's really impractical for my setup. It's a bit too small and the ridiculous keyboard tray that's built in to it makes it way too thick, so I can't be level with my monitor without my legs hitting the bottom of the desktop.
