I'm still waiting on a few bits to arrive, but enough has arrived for me to begin. I started with modifying the front of the case:
[spoiler="Button Holes Drilled and Screen Cut Out"]
[/spoiler]I have a screen cover from [mention]dominator[/mention] with an equal radius on all 4 corners that looks great. Sadly my shell makes the element sit a little high so I've been careful taking the plastic down so it sits more flush, but thats on going (its a slow job!). I didn't quite get the corner cutout as nice as I'd like but its only a small issue and not that visible.
In the photo the protective cover alignment (from me fiddling) has moved and makes it look like it sits higher, bit it's almost flush now.

[/spoiler]I have parts from other forum members and community shops etc who I need to thank (If I've forgotten anyone let me know, I'm losing track!):
@wermy - 3D printed parts
@camble - Safe shutdown (Banggood Edition) - can't wait for this one to arrive, final big puzzle piece!
@dominator - Screen Cover and Stickers
@Helder - I used your power strips via OSH
@abrugsch - Cartridge Reader
@kitsch-bent - Button PCB, Cartridge PCB, Buttons, Audio PWM board
@deadpanrobot - More Buttons
@hand-held-legend - Gameboy Shell (and yet more buttons!)
Most of the other parts I have are from China/Amazon/Ebay - I still have a few small parts left to arrive but no show stoppers right now.
I've decided with this build to not use an AIO - mainly because I just want to see what I am capable of. I plan on another though and I'll hopefully grab one of the next batch of @Kite 's AIO with the 640x480 support as I really don't think the 320 display I have on this one will cut it completely - but it'll do for now
On with the soldering!
