There's a Nintendo Switch 2, three controllers and a magsafe charging puck hidden away on my desk, all fully accessible and functional, but until I need them, they're basically invisible!
I 3D printed some legs to turn a £10 IKEA shelf into a desk shelf over the weekend, with a metal frame that I can use for attaching magnetic accessories. (No points for guessing where I hid the magsafe charger)
Overall I'm super happy with how the upgrades all turned out.
