So Microbell, you're saying that the only solution to having a reliable watercooling system is 2 PSUs? That doesn't sound feasible, ATX systems just aren't built for that. Where ya gonna put it?
Also, some water cooling questions:
How loud is it? Quiet as in 20 dba, or quiet as in 40 dba?
Is there an advantage to an external unit? Seems to me it'd be more convenient if it were all stowed internally.
Any personal suggestions on WHICH one to buy?
