Well, I guess that did stir things up a bit, kicked over onto another page and everything
Lets see...

MMZ_TimeLord: Y blocks are almost always better because you are keeping the water as close to a straight line path as possible.

True, but the local hardware store has PVC galore, I haven't seen any "Y" fittings. I find I like to have my hands on the hardware when I'm buying things.

Manifolds, unless they actually have an open area like a hollow waterblock are just as bad as multiple T fittings, because most times manifolds are one large bore with smaller splits at 90°, like so...

The manifolds I'm planning will have a LARGE open space. What I'm planning is a piece of 1.5" PVC pipe, 3-4 inches long, capped on one end and plugged on the other (in case I need to clean it out). The inlet will be whatever size comes off the Rad (probably 3/4") and probably come in via the cap end. The outlets will be around the sides, located to make the best shots at the target devices. The exact configuration will have to wait until I have the hardware in hand. However it sounds like I'm meeting your description of a 'good' manifold.
I am planning to do a high flow rate system, I am thinking in terms of an Eheim 1250 pump or equivalent. (I'm looking at a Danner Pondmaster "Pond-Mag 5" which claims higher flow, better head, slightly smaller size and similiar wattage. Anyone have any experience with these?)

sevisehda: A large manifold will slow the rate down so its *probobly* the best solution. A series of 'T's will kill your flow rate and the flow will be different in each branch. My solution was to build a CPU block with 1/2 intake an 4 x 3/8 exausts.

I don't see using the block as a manifold as being a good solution in my case - I want the blocks to be as identical as I can make them, and it would be a challenge to balance the flows so as to make them all even at best. I'd probably have to many branches as well. Also I plan on making the 'drive loop' from much smaller ID tubing than the CPU loop, so putting that in series with the CPU would impose serious restrictions.
Lastly, the mobo I'll be using doesn't have the holes to do a 4 bolt mount, so I have to do a clip-on. This cuts into the amount of real estate I have to put barbs into, so I don't think it's on.
FWIW dept, I am planning to make a high flow block with I/O at opposite corners, doing a serpentine maze with a wider center section containing lots of turbulence pins. Sort of a cross between a Swiftech and a DD Maze 3. I know this looses the benefit of direct jet impingement, but I think it will work OK anyways.

This way the block itself is a manifold. If you are cooling a dual system them Y the intakes.

This sounds like you are suggesting I SHOULD plumb the CPU's in parallel, which appears to be the opposite of what redleader is saying - I feel confused

theres really no reason to ever split CPU flow.

FWIW again, 3rotor on his website seems to be running his dual rig in parallel though it is hard to be certain from the pictures.
