Copper insides is what Kougar is referring to.
If you have full copper block for gpu, and a copper block with nickel outside, with a copper radiator, that is all copper. Its the insides that count.
If you have 1 or 2 copper blocks, and use an aluminum radiator, the different metals will cause a caustic like effect and needs to be cleaned every 3 to 6 moths. Also, if any of the caustic 'crud' gets into the pump, it can break the pump.
Same inside metals wont have this caustic gunk buildup, and extends having to clean only every year or 2, some have gone 3 years without having to clean, but iirc that was with speacial coolant.
And, yes, you can get special coolant. Look it up, read reviews, see whats right for you.
I persanally went from my own water system to allinone solutions, since the aio solutions will last as long as my computers, throw them away when the no longer work, and its about the same money as buying a new block + the hassle of draining and installing.
Of course this doesnt apply to video cards, as there have only been a couple true aio solutions made, and they are video card specific.
But, since you can buy an evga card with an aio, why not do that instead?
Ask others, a personnally made system takes time, money, and management, but cool better.
AIO solutions are worry free, for the most part, and have a 1 time cost, but dont cool as well, for the most part.
