Any "must have" items for my H20-220 Edge kit?

In another thread I asked this question, but you seemed to have missed it:
Okay so we're talking only copper & brass that could potentially mingle via water, what about this modified plenum you speak of?

As for case fans... it would help if we knew which HTPC case you're talking about and whether you plan on using lots of dust filters. In general, as you add more restriction to the air flow path (dust filters, ducting, etc) the static pressure of the fan becomes more important. If you have air flow path with very little restriction then you may be able to get slightly more performance from a fan that sacrifices pressure for cfm.

This is some very good points!
I won't think about case fans at all, until I've settled on the case & any filters, ducting etc.

Rather than getting overly worried about fan choice I would recommend you invest in a good fan controller and then you can try to tune the stock case fans to a level where the noise is acceptable and see if they're performing well enough for you.

I was of the understanding that modern mobos are sophisticated enough such that, with the right BIOS/software, one needn't bother with a dedicated controller/rheobus?

Yes, they are different processes. Neither of them are great at removing bacteria, but you've got a killcoil or biocide for that. Both remove ions, but distillation is more likely to remove non-ionic solids. Deionization is cheap, and there's no real reason why they can't use it in conjunction with distillation, but I'm not sure there's much benefit to doing both. The cheap water I bought at my local store says it's distilled and deionized
Either should be just fine for watercooling.

Thanks mate, makes sense...
I could've sworn I read that you have one or the other, but having both applied isn't possible.
But after some more reading I don't see why not, whether or not it makes a real-world difference is another matter though.

Cheap DI "&" Distilled water almost seems like dodgy advertising...
Why would they go for the "double whammy" when gains are likely minimal (certainly for most end-uses) but the costs real?

Finally, would you remove or add anything to this list:
must-have items I've ordered, or am close to ruling-in/out!
