Hi:

Yes, the bridge rectifier generates heat, but not much.
Hence attaching it to your metal case with some heatsink
grease compound is probably sufficient.

You'll note on my webpage I sell vertical heatsinks for
Geckos. Some of my customers are mounting the bridge
rectifier right on top of the tall I-beam (see the photos),
and of course the assembly is placed in the fan blast
for fantastic (pardon the pun) cooling.

The base does not usually need to be grounded, but it
just might be ground be with your particular part.
