Gameboy color pi build

[Static624]

I'm trying to put together a parts list for a color build using the pi4 (full size).
I want it in a color shell but I'm going to have the pi and attached low profile cooler sticking out of the cartridge slot for space (big pi, small shell) and was just wondering what PCBs exist for the color, like button boards and whatnot, and what parts I need minimum

Only common ground board I've been aware of is Glitch'd gamings and I'm pretty sure I bought the last one a few months back.

Fairly certain you won't be able to fit a full size pi 4 in there.

The pi will be sticking out with a low profile cooler from the cartridge area, casing will be cut

I'm going with this route as the pi is 56mm (fits slot in width) and it'll be a little Frankenstein in appearance, the ice low profile will be in theory sticking out the back
