Always been a fan of hidden setups. With limited space in the home I created and assembled a custom IVAR shelving system through IKEA’s design page for both needed storage and a place to have my PC.
I used to have the screen just standing inside the cupboard but found it to be too far from my eyes so I recently bolt-mounted a monitor arm into the bottom of the cupboard. There’s also a larger hole in the back right of the cupboard for power, display port and USB (the monitor arm has ports)
