ok, this is my entry to the modders challenge.
my idea was to make a resevoir with radiators!
i thought of a couple of designs and came to this:
tell me what you think... i have the means to make it, and think i can do it
gonna post more renders when i get home from school
edit:
its probertly gonna fit in 2*5.25 bays i think, but its not settled yet...maybe its gonna be an external... depends on how big its going to be.
