There is a gap for a ribbon cable, like this one: https://octopart.com/search?q=IDSD-20-D-06.00

I use this one a lot: https://www.kiwi-electronics.nl/aluminium-heatsink-behuizing.... I does get warm to the touch, but not close to throttling.

It seems to be available on Amazon if you do a Google Image search. I have Amazon domains blocked by DNS so I didn’t see the full URL

Yeah I was looking at that one earlier - are there holes on it to mount it to a wall? I can't quite tell from any of the pictures I can find.

Mine does not.

That's the Pimoroni RPi4 case. I don't want to spam the link a third time though.

Have the same one form eBay, works great even with the pi4 overclocked to 1.9Ghz.

Then you'll like the case I got for mine: https://shop.pimoroni.com/products/aluminium-heatsink-case-f...

From the site: "GPIO pins are accessible through the slot on the bottom of the case"

I wish there was a pic. If you find the one for Pi Zero, it shows a slot for GPIO access.

Ah that's useful, thank you.
