Say I have a Raspberry Pi enclosed in a metal case, such as this.
Would it offer any additional level protection if I put it in a static-shielding antistatic bag whenever I carry it around (e.g. before putting it in a bag or cardboard box)?
Does this offer any additional level of protection, for example from ESD damage?
Otherwise, does it, maybe, create some potential risk I may not be aware of?

Once it's enclosed in a case, there's not much need to put it inside an ESD bag - these are used when there's bare PCB exposed. The bag may add a very minor level of protection for the connector sockets however the device is much more likely to be damaged once it's in use out of the packaging.
There's no harm in putting it in an ESD protective bag, however the benefits of putting an already-enclosed product in one are negligible.
