Water Cooling Help!!!!!

I was wondering if an advanced builder could help me out. I have an extremely advanced knowledge of computers as I have been building them for 10+ years. I recently decided to upgrade to water cooling and this is my first time building a loop. My hardware is as follows:

Asus P6T Mobo
Intel Core i7 920 @ 3.2 ghz (stock cooler...will be much higher once water cooling in place)
6gig corsair dominater tri-channel RAM
1 tb WD Hard drive
2 Nvidia Geforce GTX 295
1000watt Antec PSU
Blu Ray Drive
Corsair Obsidian 800D Chassis

Water Cooling Gear:
Primochill Typhoon III Resevoir
Swiftech MCP655 pump (will be mounted into RES once it arrives in mail)
7/16" Tygon tubing (using 1/2" barbs on everything)
Swiftech Apogee XT CPU block
DangerDen Double Heatercore with 2x120mm Fan shroud

and I am planning to purchase 2 eVGA GTX 480 FTW edition video cards (they come with the copper water block installed)

My question is...what is the best/most effective way to install this loop within an Obsidian 800d - for those of you who are familiar with this case or have even constructed a rig with one. I have read hundreds of articles on water cooling and have a very good idea of how to do it. I just want some professional opinions on the best way to do this. For now, I want to construct a solid loop for the cpu and I am aware that cooling the 480's will most likely require a second loop. But, after reading about the Typhoon III, everyone says that it is designed to run two loops using only one MCP655. Can someone also explain how this is possible and what kind of configuration to use in order to cool my cpu and gpu's with 2 loops using one pump and that res?

Any help regarding this issue would be greatly appreciated... :) 

Thanks a bunch guys!!!

first off...i am a hydraulic specialist for the united states military. i work with pumps, pressure, fluid flow EVERY DAY!! ill tell you straight up that that res no matter what it claims cannot maintain 2 loops without sacrificing flow. ive read up about this res and the only possible 'trick' that this res does is that it has two inlets and two outlets going into and out of the pump which allows the pump to run without the restrictions of hose size or bottlenecks from fittings.

you are maximizing the pumps capabilities but you are still running two loops on one pump period.

get yourself a cheaper res and use the extra money on better radiators. heres a possible setup you can do if you wanna cool cpu and GPUs with one pump.

pump > radiator > cpu > radiator > gpu > res > pump repeat.

or hell....
pump > rad > cpu > gpu > res > pump

dont waste money on that crap res...use the extra money to get a better radiator or even more then one radiator. companies are in the business of making money...not ripping themselves off. if they could run 2 loops with one pump then they would be short changing thier pump department.

as for the case...radiator mounted on top...res in the 5.25 bay...and i believe the pump could either sit on the bottom shelf with the PSU or on top of the shelf.

Head over to OC Forums, there is a just done very nice 800 case just done.

^Yup. That's what I told him here:

Ahh.... I see what the OP meant now. Thank you. lol, I don't look too much at all those res's out there. I find that the Microres + 655 works quite well.

@OP: I highly recommend you get a 2nd pump with a COMPLETELY separate loop for the GPU. A MCP355(quite cheap compared to the 655) for the GPU loop.

In the end you will have:

CPU loop:
Swiftech XT/HK 3.0/EK Supreme HF
MCP655+ Microres
320 rad

GPU loop:
GPU Block
MCP355+ res
320 rad
