Montitors for your desk (pick one, I like the first one looks very modern front and back)
This one does have built in speakers too, however monitor speakers are notoriously bad so I say we see how they sound and if you want to listen to music and we find they are lacking we can always get you a set that sits on your desk later. Some people in the reviews said they are fine, some people didn’t like them. Hard to tell until we hear them ourselves.
Charger for Dock
Keyboard / Mouse for your desk (pick one, things to consider are if they have wrist support and a numpad to the right of the keyboard for crunching numbers). Any usb wireless keyboard/mouse will work if you want a different style/brand.
