Hi Les
thanx for the tip.
i've 'redeployed' ammo boxes in peacetime applications myself and i
concur they're damn-near tankproof. But that also renders them fairly
tool-proof too ....so-
Comparing notes...
How did you deal with heat transfer?
With the lids locked-down, these things are nearly airtight. Did you
cut ventilation ports? Leave the lids off?
also...
Did you thermally couple the PS's heatsinks to the walls of the ammo box?

Most connector diameters are beyond the range of hardware-store drill
bits, and they don't like chewing through steel, anyway
....How did you cut your large diameter mounting holes? a die cutter,
perhaps? 
enquiring minds want to know!

thx,
