suggestions please

right, here is what i am thinking, i am going to watercool both my gforce4 and cpu on water, almost definitely gonna b on separate pumps. i'm gonna go external and submerged for both, i only have a nomal atx case wish i had a nice big server one...... but nm.

i have a space that is about 0.3x0.5x0.5m big to use as a resevoir [75litres] [16gallons]. now is that overkill on a resevoir size? if so what would u suggest for a resevoir size?

with a res that size would i really need a radiator? cos to raise the overall temp of 75litres of water [i.e. 75kgs] it is gonna take 4.2*75*1= 315kJ and with a processor and gforce 4 going at 0.2kJ/s [0.2kW] tops it is gonna take nearly 30mins to heat up. with a 20litre res it is gonna take 7mins to heat up 1 degree, and the water should lose that pretty quickly, right?

i'm also gonna b using a maze3 it seems, as it is gonna cost me more to ship a dtek block than the block itself costs dammit. and an ocpc atlantis block for the gforce4
atlantis on gforce 4 (http://www.coolhardware.co.uk/ocpc/atlantis/GF4/G4atlantis_rev2.jpg) (does it look ok?]

what sort of gph should i b looking for if i am only cooling the cpu or gforce4? i was gonna go for a pet shop/fountain kinda one, due to availability and links i have.

also, 75litres of DI water is gonna cost me a lot if i go for that much, u know those brita water filters, how good r they at filtering? would the water from taht+some methanol+water wetter/purple ice/other b good enough.

plus i am trying to keep all copper, so as to avoid any battery corrosion effect and use 1/2".

any comments/sugestions/etc etc very welcome, i want to get this right!!
thanx.

well then. its true that if you use enough water in a resevior, you dont need a radiator, but, i'm not sure if 75 Kg of water is going to be enough to go resevior alone. also, if you do that, the only way the resevoir can cool itself is if it is open to the atmosphere to evaporate. when that happens, you dont want to have things like water wetter in there cause it stinks, and NOT methanol cause it will destroy various aspects of your health. only use those addatives in an enclosed system. what you could do, would be to stick a radiator inside that huge arse resevior. then you could put addatives in that system, and rely on the radiator to transfer the heat to the resevior....
