Here's a shopping list:
Case: Danger Den Tower-21
Motherboard: XFX nForce 790i
CPU: Intel Core 2 Extreme QX9650 Quad processor
Memory: Corsair XMS3 DHX DDR34GB Dual Channel Memory Kit
Graphic cards: 3 Nvidia GeForce GTX280. 2 from PALIT and 1 from BFG
Power Supply: Corsair HX1000W
Hard Drives: Western Digital VelociRaptor
Watercooling supplies: Danger Den
Step 1: Building the Case Danger Den's Tower-21
parts come labeled and each set of screws come in a separate bags. Danger Den's kind enough to throw in white gloves, here a tip..use them! When I started without them I got fingerprints everywhere. This case is a showstopper so treat it like one.
Step 2: Water Cooling Intel's QX9650
Step 3: Filling the Tower
Lets start cooling it all down. Danger Den is always on the cutting edge when it comes to water cooling. Double D is always refining their water block designs and pushing the limits of the water cooling performance. On the inside front of the case I install the Danger Den's Black Ice GTX360 with three 120mm fans from Cooler master. I take the DD / Laing DDC-12V pump and add the DDC Acrylic Top to it. The next part of watercooling is setting up the GPUs
Step 4: Three Nvidia Geforce GTX280 SLI Setup
Here are 3 Nvidia Geforce GTX280 2 from Palit, and 1 from BFG. Even though the cards are from different manufactures and different specifications(the Palits are stock and the BFG came with the waterblock pre-installed) they will work together in SLI. Atfer I install them I'm going to use the Nvidia control panel to match the two stock cards with the overclocked from BFG. First I have to convert them to watercooling.
Step 5: Water Cooling the Graphic Cards
Here's an overview of process, Use the pictures as your guide:
Unscrew and score the stickers to remove the cards back plate, pry up the front housing and unplug the fan. wipe off and replace all the thermal paste and heat tape. Test fit the Tieton waterblock . Sandwich the card between the block and the new black plate (the black horseshoe) and screw it together, being careful not to over tighten.
Step 6: Installing Water Cooling
The first tube is the fill tube (where the coolant is inserted) connect it to the top of the pump.
Next attach a tube from the top of the CPU water block to the first graphic card.
Stagger the SLI custom fittings on the GPUs. On the last GPU card attach it to the Radiator.
Attach another from the bottom of the CPU water block directly to the pump.
The Last one, on the pump add a tube going from the pump to the radiator.
When I first turn it on I have a huge flash light and paper towels stuffed in areas that could have a leak. If there is a leak (rare) power down immediately and give it a few minutes to a couple of days depending on the volume of damage.
