Is it possible to attach a heat-sink to the Raspberry Pi Zero W whilst it is within a [Pibow Zero W](https://shop.pimoroni.com/products/pibow-zero-w?utm_medium=cpc&utm_source=googlepla&variant=38473032906&gclid=Cj0KCQjwtpDMBRC4ARIsADhz5O5nhMwc54RoDbEWy2hSYhgXanQsnjg9GOO0Hdk7l-9ptW3W-qq_2vkaAgyxEALw_wcB) case? I can’t tell from the picture whether there is enough clearance as is, or that it would only fit when the clear acrylic layer is removed.

The heat-sink in particular I was using as a reference is [here](https://shop.pimoroni.com/products/heatsink), however I have no idea if it fits the Raspberry Pi Zero W.

I have the 6mm one on my Pi Zero and it will not fit in the PIBOW case. Not without leaving the top layer off. Or cutting a hole in the top layer.
