MOTM

I know what you mean about a nice PSU tutorial for our ever growing MOTM 
systems. My solution (which addresses your questions 2b and 3, in a way) was 
to use a larger Power One supply (I think the number is an HBB 15-1.5A) which 
supplies almost double the power of the MOTM 900. I was able to mount it on 
the 900 front panel with very little trouble -- I did have to drill new 
mounting holes in the aluminum frame of the Power One unit (being careful as 
to not drill too deep and accidentally drill into the transformer). I also 
had to be rather careful to locate the Power One unit in the right horizontal 
position since there is very little clearance on the sides with this wider 
unit. I can't imagine a larger unit than the HBB size being able to fit 
against a 3U FP -- of course you could always go case mounted.

I was able to use the MTA power block without any problems but I also added a 
barrier strip since I wanted many more PSU connections.
