A PC built into a keyboard without a display, like the Raspberry Pi 400, starts making a lot of sense with Meta Quest HDMI Link running on the most popular standalone VR headsets.

The Raspberry Pi 400 is a roughly $70-$100 keyboard with a Raspberry Pi 4 PC inside. The keyboard PC features a pair of Micro HDMI ports for display, a USB-C port for power in and three USB-A ports for attached devices.

Paired with a VR headset like Quest 3, I’ve used retractable USB-C cables to make the connections more manageable between keyboard, power, and headset. The setup is completed with a mess of USB hubs, micro HDMI to HDMI adapter and a Shadowcast 2 capture card.
