# 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! ![raspberry_pi_hero-screen-site.jpg](https://cdn-learn.adafruit.com/assets/assets/000/114/147/medium640/raspberry_pi_hero-screen-site.jpg?1660583582) ![raspberry_pi_ports.jpg](https://cdn-learn.adafruit.com/assets/assets/000/114/148/medium640/raspberry_pi_ports.jpg?1660583641) ## 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. ![raspberry_pi_cables.jpg](https://cdn-learn.adafruit.com/assets/assets/000/114/149/medium640/raspberry_pi_cables.jpg?1660584092) ![raspberry_pi_sd-card.jpg](https://cdn-learn.adafruit.com/assets/assets/000/114/150/medium640/raspberry_pi_sd-card.jpg?1660584253) ## 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. ![raspberry_pi_feet.jpg](https://cdn-learn.adafruit.com/assets/assets/000/114/151/medium640/raspberry_pi_feet.jpg?1660584417) ![raspberry_pi_compact-back.jpg](https://cdn-learn.adafruit.com/assets/assets/000/114/152/medium640/raspberry_pi_compact-back.jpg?1660584669) # Parts ![](https://cdn-learn.adafruit.com/assets/assets/000/114/154/medium800/raspberry_pi_parts.jpg?1660586758) ### Full Size Wireless Keyboard with Trackpad [Full Size Wireless Keyboard with Trackpad](https://www.adafruit.com/product/2876) The quick brown fox jumps over the lazy dog.  The quick brown fox jumps over the lazy dog.  The quick brown fox - sorry!
