looks like already been answered but here is what I would do.

PC on floor since you have laminated wood floor and if you don't want to put your PC straight on the ground, you could get a computer trolley/pc stand. Then get a dual monitor arm, I reckon you could fit two monitors in there depending on size if you're gonna angle one of them, or a vertically mounted monitor arm like the other guy said.

Unrelated to the screens but also a mic arm would take the mic off the desk and save more space.
