  The last PSU I used was from an old VCR. It is a switching PSU and had 
5V and 12V. It handles the CC3 board, 3.5" floppy drive and add on 
boards but I did have to add a 12V lamp to the 5V supply line to keep 
the current drain to a level that keeps the PSU happy.
  I don't know how easy it is to find old VCRs now but, when I got this 
one, those things were constantly being tossed and replaced with new 
ones. That one is about half the width of a 5 /14 drive and about the 
same thickness and length.
