In need of a teeny tiny desktop computer? While you may have difficulty buying one off-the-shelf, you always have the option to make one yourself!

Here is how.

Like any project of this nature, you are going to need a few bits and bobs. For this build, you will need:

The first thing to do is to load the STL files and print off the various 3D parts required. You can find the design here, or have a go at creating your own design. 

The provided schematics are for the main computer tower, as well as, the casing for the VDU. 

If you don't have a 3D printer yourself, ask one of your friends who have one, or make friends with someone who has a 3D printer.

Depending on the speed of your 3D printer, this will take a few days to complete. With the 3D printed parts complete, sand them down and paint as required.

If you decided to paint the casing, once the paint is dry you assemble the main computer housing as shown in the video (or according to your own design).

The next step is to cut a piece of clear perspex, mark out and drill some screw holes and affix to the main 3D printed (and assembled) casing. Now, remove the perspex piece in order to add the gubbins to the tower.

Next, grab your fresh-out-of-the-box LattePanda Alpha 864s and SSD memory card. Attached the SSD card to the LattePanda board as shown.

Now mount the LattePanda board (and SSD memory) inside the 3D printed computer tower casing. Refer to the video to ensure you position the LattePanda correctly.

With this stage complete, it is now time to extend the USB ports to the main casing opening. For this, take your USB cables and USB connectors (or USB extender cables if you'd prefer).

Build a USB port holder using a piece of PCB board and wire up as shown. Now mount to the main casing and plug in the USB cables to the LattePanda board, as shown. 

Alternatively, you could simply connect up some USB extenders.

Once complete, the next step is to add some RGB LED strip lighting to give the computer tower some added coolness. With the strip lighting in place, wire up to the Arduino Nano, as shown.

Now the Nano in turn to the LattePanda board, as shown in the video.

Unfortunately, no code is provided for the LED strip lighting sequencing for the Arduino Nano, but here is a useful tutorial to get you started. 

The next step is to build the on/off power switch for your mini-PC. Take your mini switch and 3D printed power button parts and assemble as shown.

Your tiny PC is pretty much finished at this point. Now re-attach the perspex side panel to complete the tower assembly.

The last stage is to assemble the monitor. Take your 10.1 inches (25.7cm) IPS display and mount inside the monitor 3D printed parts you printed earlier.

Now simply connect the ISP monitor to the main tower, plug in the power for the LattePanda board and fire her up.

Finally, simply sit back and enjoy your masterpiece! Well done you.
