Cool. I'm looking into those.
Here is the loop I'm considering now
Did quite a bit of research on the pumps yesterday. In the end the contestants were the Innovatek Eheim HPPS, the DDC 3.2 (MCP355), and the MCP35X.
There is very little performance data for the Innovatek Eheim HPPS
. The only piece of information I could find is that at zero flow it puts out 2.05 mH2O (207.72 mbar, 3.10 psi). That is about 45% of what the other two do. What I really wanted to find out was a Pressure vs. Flow Rate curve for it, but I did not.
The second contestant was the DDC 3.2
(MCP355, DDC1+). It provides okay performance out of the box (yellow line), but when used with an XSPC Regular (non-reservoir) top (green line with diamonds) it really shines.

Lastly there is the MCP35X
which has a slightly flatter performance curve top with a slightly longer reach. The yellow line on Martin's chart above should be equivalent to the orange line in the one below. From that you can compare the green line with diamonds above with the red one below. Or if you want 17.5 LPM is about 4.62 GPM.
Innovatek Eheim HPPS
The big advantage of the Innovatek Eheim HPPS is that it is said to be very quiet. On the negative side there is little performance data, the data that exists compares it very unfavorably to the other two. It is also rather large at 125 x 55 x 65 mm (4.92" x 2.17" x 2.56") and has odd fittings.

DDC 3.2 with the XSPC Regular (non-reservoir) Top
Choosing between the MCP35X and the DDC 3.2 with an after-market top, such as the XSPC, is more difficult. The performance curves look very similar to me. With the XSPC top, both sets give you G1/4 ports. the difference seems to be that the MCP35X can be PWM controlled from the mobo (4 pin connector) from 1300 to 4500 RPM, and the DDC 3.2 would have to be undervolted (down to 9V(?)).
I'm leaning towards the MCP35X as I'm hoping I can create a profile in the BIOS that pumps it up on load automatically. It adds to the coolness factor and helps control noise.
The emphasis on the performance data is because while I initially wanted to do a CPU only loop, I have started to consider adding the GPUs and perhaps even the mobo and memory -- it would be a decision based on looks rather than anything else, but it is something I may go for. Having a stronger and smaller pump would allow me to keep that possibility open and even, God forbid, do a dual loop *cough* *cough*
Will need to see how noisy they are, but since the pump is smaller and will be hidden I could suspend it and box it.Edited by QuietMan - 10/30/10 at 10:55am
