I've done this very thing (starting at the 512E step).  The power supply
seems to be OK but you will almost certainly need to add a fan to keep
the temperature down.  (I use a Kensington System Saver Mac which also
has a surge protector and moves the power switch to the front.  Switches,
I should say, as they give you one for a hard disk or other peripheral
and one for the Mac itself.)  I tried a MacChimney hoping for a silent
solution but it didn't seem to do the trick (and when you add a hard disk,
you probably won't notice the little extra noise made by a fan on the Mac
itself...)

Hope this helps.
