Orange Pi5/5B Metal Protective Case, Only Compatible with Orange Pi 5, Orange Pi 5B Single Board Computer (with Antenna)

Does this case act as a heatsink? specifically, does it come with thermal pads to make contact with the cpu and ram chips to dissipate their heat?

One reviewer said the Wifi antenna cables don't fit the connectors in the case. If so, that defeats my whole purpose. Is it true in general?

Are the antennae removable? Using a usb wifi adapter with its own antenna since the nvme slot is occupied by an ssd.
