Now it’s time to finally connect all these pieces to get the planned case, as mentioned in previous post I’ve worked on the front panel with a dremel, here’s the result:

Raspberry case (front panel)

I’ve created a small cable extension so I can insert the PSU on the front panel that it’s internally connected to the USB hub inside, it’s also well insulated from the case as well.
On the left side of the picture (it’s flipped) you can see 5 holes for the usb ports, on the right side there’s the ethernet connector hole and the hole for the two usb ports coming from the Raspberry, on the upper side of the two raspi ports there’s a circular hole used for getting the usb cable inside the case once connected, maybe it’s not that nice but it’s the best compromise for a very clean solution.
I did it without a CNC or a press, just some aluminium working with a Dremel. I’ve firstly cleaned the external surface with some sand-paper and then finished with an abrasive slurry to get a clean result; I must admit I can refine it even better to get a reflective surface but in that case a silly scratch might waste hours of work so I’ve decided to get a light opaque surface.

I’ve finally tied usb cables inside to avoid weird movements, this image shows you the front panel with the internal base, the Raspberry Pi and the USB hub

Power supply cable extension is connected on the front panel, it passes under the base and it connects to the USB hub (the red and white cable on the top right corner).
USB cable used for powering up the Raspberry is connected to the port N.7 of the USB hub, I’ve just tied the cable to avoid strange movements.
To connect the Raspberry and extend ports with the hub I’ve connected a common USB cable from the bottom USB-A connector on the Raspberry to the USB-B connector on the hub, the cable enters inside the case through the small circular hole seen previously on the front panel, passes under the PVC base, and connects to the hub. Like before the remaining cable is tied together to avoid internal mess, a cleaner solution might be to create custom cables with a proper length but as I’ve told you before I’ve just used spare parts lying around at no cost.

Now I can place the plastic pillars  around the Raspberry to fix it a little more and I can slide the front panel inside the aluminium case

And finally……………… Here’s the result:

Raspberry case (final assembly)

I’ve also drilled the front panel between the power supply connector and the two Raspberry usb ports, I’ve put a small piece of red plastic in it so I can see Raspberry internal lights coming out. USB cable in the front is not that nice but it’s the only solution I’ve found to get 6 available USB ports from the Raspy and an internal power supply coming from the hub.

Screws are black but I’ll surely switch them with something more bright, I didn’t had decided for a common color to use on the front and the side panel.

In the next post I’ll publish more photos of it but this seems to be the final case, please feel free to ask your questions or share your comments with me

    Hoi! A very nice case hack. One question please. I see the cable between the Raspberry Pi and the USB-Hub. Have you a name for it? I would like to order it from internet. Thank you.

    Best regards

      The USB cable used for powering the Raspberry is called microUSB cable (Type A male plug < -> microUSB), really popular if you have an Android or a Blackberry phone, or even newer photo cameras.
      The cable used for extending USB ports from the Raspi to the hub is a common USB A-B cable (Type A male plug < -> Type B male plug), the most common usb cable on the Earth, the same one you’ll use for connecting a PC to a printer for example.
      Both are available in every mall or electronic shop in the “computer/cell phone” sector, you don’t need to purchase something special from the web even if a shorter cable or a 90° plug could be better… let me know if you’d like to have more details

    Hi Ben,

    your answer is perfect, I found it on amazon. I wish you a nice weekend.
