that is one EPIC cheerios box you got there, grimm. I APPROVE (
even though i didn't get any credit 
).
you did it to me again, grimm.

make sure to shrink tube any exposed wires or connections when you get a chance. if you can use a lot of it i'd get it at hobbyking.com... and wait for a month for it to come in (real cheap, though). if you only need a little, any hardware or auto parts place should have little packets for a couple dollars.
liquid tape, electrical or plasti-dip spray would be good for insulating and waterproofing on/in the back-side of your connectors as well.
if you have any problems down the road with your fans you might want to consider eliminating those connectors and hard wiring them. not that i foresee anything with them pretty much being stationary... but sometimes connectors just come loose.
i want to do a write up on how to wire up power boxes (outlets in the walls, switches, dimmers, etc.). i've got one on how to wire up a four outlet box to have a dimmer on one outlet and another outlet that's dedicated for $8 if you happen to have a pc power cord handy that i posted on a couple r/c forums. if you want, i can throw up a couple write-ups within the next week. then you could put outlets inside your stand and only have one power wire coming out. would be great for drip loops, tidiness (at least outside the stand, lol) and such, too.
given the exact same components...
amperage doubles in parallel
voltage halves/doubles in series
so... a 24v power supply rated @ 20-30% higher amperage than one of those fans would give both fans their 12v but the amperage would be what's on the fan label give or take. (they'd split the voltage, so you'd have to double it. hence halves/doubles.)
a 12v power supply would have to supply twice the amperage to gain the same result and the fans would have to be wired in parallel so each of them receives the full 12v from the power supply. in this case, they're not sharing anything... the electrons are traveling down different roads... so the amperage of each fan is added to the total load.
ohm's law states that P (power or watts) = A (amps or flow) times V (volts)
so let's say each fan is rated at 100mah (milli-amps per hour) @ 12v
in series that would be 24v times .1amp equals 2.4 watts
in parallel that would be 12v times .2amp equals 2.4 watts
any electronic product with 80% efficiency is about top of the line and heat increases exponentially as you reach the upper limits of any power source. that's why you'd want at least a 20% buffer... because heat is the first step/sign in/of degradation... and once it's done, it's done... and only gets worse from there.
just some things you might be interested in or just in knowing. i know how you like the tedious work,
don't we all?
back to seriosity... this thing is looking fabutastilisious....
for the
so far...
... keep up the good work.
