Completing my new rig!

[Circuitbreaker8]

So I finally upgraded my computer! I've had my A64 3400 Claw, DFI LanParty nF3 250Gb, and Gigabyte X800XT 256 for over a year ( longest for me! ) They're still GREAT, but I decided I want to upgrade my rig. Heres what my new rig looks like...

AMD Opteron 170
DFI LanParty nF4 Ultra-D
ATi Radeon X1900XT-X 512Mb
(Rest of specs in sig)

Now, I have a couple more things that I want to get

A good heatsink/fan combo for OCing my Opty or water cooling
New case w/ good cooling ( Currently have a Cooler Master Praetorian which is ok )
2Gb RAM ( I currently have 2x512Mb OCZ Platinum 2-2-2-5 )

Now, if I were to go with a mid to high ( not super extreme ) end water cooling system, how much would I end up spending? If not, whats teh best heatsink out there for 939 thats quiet but effective?

I think i've already decided on the case; A Cooler Master Stacker! That thing looks pretty sick and I heard its really good.

As for the RAM, I think i'll just end up going with 2Gb OCZ Platinum BUT I don't know if I want to get instead of a new case/heatsink OR get it first and have the others wait.

Looks like you have a good idea of what to get. I just upgraded from a x800xt to x1900xtx in the last month, you will notice a pretty big difference.

as a water cooling loop:

Something like:
Danger Den D5 + TDX Waterblock combo - $110
Danger Den Maze 4 GPU
120.2 or 120.3 Rad - $35
Swiftech microres - $20
1/2 ID 3/4 OD Tygon tubing - $20

That would probably be the cheapest you would want to go. Id check out the Water Cooling forum here at the [H] for more info and advice.

A CM stacker is a good choice for a case.
