Coffee-maker style thermal fuse,
http://www.radioshack.com/product/index.jsp?productId=2062259
I just install this somewhere in a project's chassis, connect it
to line in, and the fuse opens whenever the temperature inside the
chassis exceeds 262.4F? Reliability?

That's a bit hot for a "system chassis" protection!
That part is normaly used for transformer protection (burried in the
windings somewhere) or for heater type things proteciton (washer/dryer
heater over-temp protection, or as you say, coffee maker machines.)
It's a one time thing too, once it opens, it stays open.

These thermal fuses might blow at a lower temperature than specified,
especially when they are used at elevated temperatures (thermal stress).
Note that you can not solder these fuses without a decent heat sink. I
would suggest a bimetal thermostat fuse (Klixon) for your application.

Custom lighting fixture for a rep cage, must be left unattended
for long periods. Sucks to have the house burn down when I'm
away. At least, overheating can discolor reflective surfaces,
dropping the light output substantially. Better to have a $2.00
component spliced in with a terminal block for easy replacement.
