- good speakers (Dynaudio studio monitors)

- decent headphones (Beyerdynamics dt770 pro, lasted me over 10 years now with just one cable and two cushion swaps. Sadly the cable is soldered.)

- cheapish 2nd monitor (used should be fine, but I wanted a smaller 15" one so I got some usb-c one)

- vacuum robot (cheapest without cameras, but with lasers)

- milk foam thing

- budget chefs knife + sharpening stick

- bluetooth/dongle headphones (sadly overpriced for the cheap feel, but the only ones easy to switch from dongle to phone/bluetooth: logitech h800)

- magnetic usb cable for headphones and wireless mouse

- any cheap midi keyboard if you like to play (but none of the rubber-pad ones). Decent piano without 200gb downloads and unlimited tweakability: https://www.modartt.com/pianoteq

- cheap macro lens for your phone ("Foldscope" paper microscope with backlight if you want to up the game)
