After many hours of gradual refinements, I've completed a TinyLlama 2 (with wavetable selector) embedded version of a 3d printed mini IBM PS/2 25 that I had designed last year. Here are the STL files and list of materials - Printables - and here are some more detailed build instructions - Instructables. It's got built in power supply, LCD monitor, audio amplifier and speakers, case fan, front panel SD card access, back panel with the a TinyLlama control board, and a big red switch to turn it all off.
There are several pieces that are different for the TinyLlama - mainly the electronics board for mounting the PCB and holes for the ports.

To use the internal power supply it required adding 5V connection to the Llama. This was done by very carefully soldering in some connections at these points:

. Thanks to Aaron707 for working this out. Here's what it looked like on mine:

Here's a photo of all the electronics before they were mounted to test:

The PS/2 25 has a disk access light I used the circuit that Eivind had suggested to control this. I connected this to the HDD Clicker from Serdaco to add even more authentic feel for the experience.
Here's a bunch more photos of the internals. It's not easy to get good camera angles in there, but I can try to elaborate if there's any questions.
It's been a very fun project - thank you Eivind for your great designs and help, and thank you Aaron707 for sharing this project and your thoughts!
