Help Finding Thread Please?

[MartinW]

I have spent most of tonight searching everything I can think of and cannot for the life of me find a post, or possibly an entire thread that I know I have seen before - I'm SURE I'm not going mad!!

Someone here has taken a broken A600, removed the motherboard (or it may not have been there to start with), made a 3D printed frame and backplate, IN WHITE, and used that to interface a RPI3B+, USB, power, the A600 keyboard etc. without harming the original case at all.

This is not the link to the MISTer one that has 3D printed parts in black.

If anyone can point me to this I'd appreciate it please. I have just ordered a 3D printer and while I'm a long way off being able to do something like that I wanted to take another look at the picture(s) for inspiration.

Thanks.

[EDIT] While the thread may be older, I've seen it in the last few months so chances are it cropped up under "new posts" relatively recently.
