That shows you will need a decent water capacity for cooling ( or cooling liquid ), and run offs for the cooling in the bed, a pump, and probably a card that can controll the pump.
If I add all these components up will I still be able to achieve something of a reasonable size+weight that I could fit in my 12x8 shed? Or do I have to find an industrial unit to run this sort of machine? I know I am asking for a lot here but if you think I am being impractical then I guess I will have to leave this bizarre obsession of mine lo.
