- The slot on the rear (right of the 3.5mm socket) allows a USB cable to pass from the Pi's port back into the case (if using a 2.5" hard drive or SSD and USB adaptor).
- HDMI ports are converted from the Pi 4's Micro HDMI to full size HDMI for convenience (there will be two - waiting on a part). USB-C and 3.5mm (incl. video) ports are as on the Pi. A removable blanking plate (far left on rear) is provided should a user want to add an additional port.
- On the front of the case are vents to allow air in and there are vents on the top panel, above the Pi's CPU and the drive mounting location, to allow warm air out.
- All external screws are on the bottom of the case (assuming it is used horizontally as shown).
- I'm still waiting on a few parts to complete this first prototype. Once I've received and fitted them I'll post some more photos showing the completed item, including some interior photos.
- The case is designed to be relatively easy to 3D print. I'm still tweaking the model but I'm not planning any major external changes.
