Two 2560x1440 screens at home. Three smaller screens was another option that I have at work, but this was cheaper. They're budget screens; I don't need high quality ones to look at colour coded source code.
Simple keyboard and mouse. Wired ones because I was worried about eavesdroppers and because why not, they never leave my desk anyway. I also use a mousemat.
Bluetooth headphones (I'm not consistent on the wired thing).
A lot of notes, letters, pens, some books, sometimes empty plates or boxes.
