Liquid Cooling Maintenance & Upgrade?

I'm not completely sure what pumps they use, but you can email Alex or just give tech support a call to ask what tubing they use or simply replace it with whatever tubing you buy. Just make sure you buy the right size, but once again I'm unsure of the diameter they use.

Distilled water works as a great coolant. It really just depends. You can buy mixes, with or without color if you want. But you'll get pretty much the same performance out of them all.

Some pumps, like the D5 are power houses and can support a 480mm Rad and a 240mm rad no problem. But I'd only add a 480mm if you're planning on cooling your GPU's also.

The Hailstorm II comes in the Corsair 900D case, which is a monster case made to house several radiators. I myself use the 900D, though it's not a DS, I did it myself.

I run a dual loop though. I have a 120 quad (480mm) and a 120 dual (240mm) on the bottom cooling my three cards, but they have their own res and pump, while I have a 120 quad (480mm) on the top cooling my chipset, ram, and cpu.

It really just depends on the amount of equipment you're cooling, the pumps your using, etc.. on if you need a dual pump set up, or a dual loop set up.

I realize I didn't give you a straight yes or no answer on really anything, but the additions take a little more work.

The actually maintenance - Drain it, flush it with distilled water (if you want), and fill it back up with either fresh brand name coolant (I prefer Mayhem) or some distilled water with an antifungus (I like the coils personally).

Sorry for the late response.
