MOTM

Guys,
  I want to build a spring reverb module and am looking at the Paia Hot 
Springs as the only kit reverb out there..  I (of course) want to build it 
behind a MOTM panel so It is fully compatible with my system.  Do any of you 
who have built this or know the dimensions of the reverb tanks think that 
they and the circut board and the jacks and pots needed will fit behind a 2u 
panel..  3u??   All I need to know is if anyone thinks that this is 
possible.. Then I'm going to order the kit.  I know I can make it work but 
any real info would be helpful.  I should keep spring reverbs away from power 
supplies right??
Thanks,
~Steve
