Smallest Power supply??

I found a very nice cabinet for a control box, however it just does not have
quite enough room for the switching power supply I have been using.

Any suggestion on who has the smallest 24 volt, about 6 amp power supply for
sale?

I have 3 inches of height available. And need the smallest footprint
possible. I can also use separate components. Easier to tuck into the corners.
Unit will have an internal fan, and is running 3, XYLOTEX's for this
application.
How small physically of a toroid would provide what I need? Source?
Other suggestions?
Thanks,
bill
