I primarily game on PC. I also own a Switch and a PS5, and most major consoles released since the NES.
All my old consoles live in plastic bins with all their relevant cables and controllers. Most have flash carts or mods that allow me to load ROMs off external storage. When I want to play some SNES or PS1 I just pull the relevant box off of the shelf and plunk it down by my RetroTINK or my PVM.
