# DIY Pi 400 Keyboard Case
## Overview
https://youtu.be/f1t6kB6299E
## Build a PC case inside a Keyboard
Plug into any HDMI display! Browse, work, watch streaming video and code, just like any computer!
Most single board computers, like a Raspberry Pi, fit right into the small form factory of a keyboard with built-in trackpad. Easily detach the keyboard to access additional GPIO hidden inside the case.
Ports on the back allow you to attach accessories and keep them tidy!
## Room to grow
**This case works with both Pi 3 or Pi 4 'shaped' boards!**
The case has plenty of room to store extra wires. Fan mount with a ventilation grill keeps the PC cool with enough space to add a heat sink.
## SD Card Slot
The Micro SD card slot is accessible on the front so you can always swap it out.
## Grippy, stable base
Add a set of rubber feet to the bottom so it’s nice and grippy.
The mini fan provides air flow to the board so it stays nice and cool.
## Cable Coiling
With the extra space you can pull out the HDMI and microUSB cable for connecting to a display and power supply.
