Well, there are some that sells few goodies like case windows, cold cathode... stuff like that also two wb Swiftech and Magnum but everything is qute expensive.
But I'm in the process of starting business of making waterblocks of all kind, and I'm confident that my products will outperform most stuff out there.
Here is some of my work:

Btw. I'll show new Gf4 prototype water block (gpu+ddr) when I'll go to and try to break (well I pretty sure
) amdxp/4200 3dmark record with 10°C water on cpu and gpu, everything voltmoded
Tons of others pics on that link in my sig.
And you don't wanna use Y spliters for cpu and gpu. You need all the flow you can have on cpu, just put gpu block after cpu, and don't think that gpu will get much hoter water in the block (that what most people think) well let me tell you I have temp probe in inlet and outlet of cpu block and the difference is 0.1°C so minimal, of course this is the function of the flow rate, so bigger flow lower deltaT between inlet and outlet.
