My loop uses a combination of Copper, Brass, Nickel, and Silver (kill coil). I want to use Distilled water for maximum cooling performance but I'm also concerned about harmful interactions between metals. I know mixing Copper and Aluminum is dangerous but I don't know what to think regarding mixing in Nickel and Silver.

why not use a different coolant with faster thermal transfer rates? water is good because of capacity, but it doesnt pull heat as fast, so as long as your loop has enough performance to remove then heat from the coolant, the heat capacity of the distilled water will not be beneficial. distilled water has performance benefits when your pump and rads cant remove heat fast enough, this allows the water to hold more of the heat itself inbetween heavy load periods and thus can remove the heat at a later time without dramatically raising the temperature of the loop.

Copper + Aluminum is the combo you want to avoid. These 2 metals LOVE to trade ions.
You will still have some ion transfer in the loop you described above, even with distilled water. The metals you are using will have a low corrosion rate. An anti-corrosive will just slow it down. It may allow you to change the coolant after 2 years instead of 1.

why not go stainless and be done with it ??Or why not go completely copper, or completely aluminum, or completely gold? Obviously using the same metal throughout would be the only sure-fire way to avoid corrosion issues but I'm asking about anti-corrosion measures for mixed metal loops.

If you're going to have that many metals, anti-corrosion is likely a must. Dissimilar metals can cause galvanic corrosion, if anything ionic gets into the distilled water, as you'll basically create a weak battery.
Another thing to consider is the clearances you have with all the metals. All those metals expand and contract at different rates and temperatures, and that could weaken joints and cause a failure.
I'd consolidate and go with one metal only, and use an anti-microbial agent in the water. Maybe colloidal silver, but I would dig into whether your tubing would galvanize with silver.

I'm currently flushing my system with distilled water and Primochill Sysprep/leak testing it so I have about 6 hours to be convinced not to go with distilled water.

I don't recommend using a dye since I've heard it can stain your blocks. I got a pre-mix that has all the anti-corrosion and anti-microbial stuff already in it and I haven't noticed any staining.

There's more info on it. They also have an Aurora coolant which looks pretty sweet, although I've never tried it

Best solution
Distilled water provides the best heat transfer. When you start adding solutes to the water, the thermal efficiency drops.
Dyes are fine. It will likely stain tubing, but you are tossing it out eventually anyway. I've never seen dye stain blocks. Coolants can particulate out at high, sustained temps (24/7 Folding, etc) and clog pin matrices in some blocks. Just FYI...this includes some Mayhems.
Brass, copper and nickel are typical watercooling component metals; avoid aluminum. If you have to run aluminum where it comes in contact with water, you'll likely want a coolant that provides anti-corrosive properties, or glycol solutions that are similar to automotive coolants, but less concentrated.
