What equipment to Watercool a 4800+ X2 and 7800 GTXs in SLi?
 

Hi guys. I am putting together a new computer, and it's going to be my first watercooled PC. I want to watercool mainly because I want total silence...but I also want to run a dual-core processor at FX-57 speed. I'll use this computer for gaming mostly. My budget is high, and it is not limited...I just want the best equipment. I plan on building this PC in a Soldam case, and I'm willing to modify/cut it up.

Here are the main parts that will make up the computer.

-A8N-SLI Premium (also have a DFI LANPARTY nF4 SLI-DR, but I'll probably use the A8N)
-AMD Athlon 64 4800+ X2 Dual-Core Processor (Overclocked)
-Two 7800 GTXs in SLi
-2 or 4 WD Raptor WD740GD HDs in RAID0, and 1 Seagate Barracuda 7200.8 400GB




I have been reading about the different types of systems...low flow, and high flow, but am undecided, although I know to basically not mix them. I've seen some massive 3/4" OD tubing in some guys systems, and I seen some 1/4" ID tubing in some. I want to watercool my processor, chipset, and both video cards. I'm still undecided on what pump and radiator I'll use, and what blocks I'll use. I want to fit everything in the case...would it be OK to cut 2 120mm fan holes in the bottom of the case, and mount the radiator on the bottom? Please let me know what you think...what dia tubing, low/high flow, what pump? Thanks guys!

I was thinking of...

Dual 120mm Radiator
Innovatek Eheim 12v Pump (or two if needed?)
Danger Den NV-78 Block or Innovatek Cool-Matic NV40LT
Danger Den Silver TDX Block
Danger Den ASUS A8N MAZE4 Chipset Block

BEst not to mix the innovatek and Dangeden parts as innovatek will be designed around small-bore tubing and Dangerden would normall by used with 1/2" ID.

If you're on the 1/2" ID then swap the Eheim 12V for a DDC Pump and the get a Thermochill or Black Ice.
