You could always save some amps and weight in attic by using the fish tank pump and water for cooling the spindle.? Sure Nemo and his mates won't mind.! . . . Then when it's time for water change then use it for flood cooling. . Lol

Many moons ago I was working at a large data centre associated with a UK bank... the cooling system for the mainframe did indeed run outside to a large bank of evaporators and the condensate was stored in fishponds which, because it was well aerated and at a controlled pleasantly warm temperature, housed a startling variety and size of tropical fish...

On a serious note though, how thick are the joists in the attic space? Is it a sanctioned conversion or have you just migrated to it?
