I know you said no kits, and I believe the universal kit you were using was the Larkooler Universal kit, but you might still take a look at this...

I have been running it non stop for almost 4 months without a single hiccup. Its about the same price as the swiftec radiator/reservoir/pump combo and includes the CPU waterblock. This kit, unlike the universal, is all G1/4 so that should cut down on compatibility issues.
The swiftec is pretty cool, my only concern is with the fill port. Seems like if you mount that in the top of the case, the fill port will be pretty inaccessible, but I may be wrong. I do like the idea having it all in one centralized package.
